The Function Of Cellular Respiration Is To – You know that cells are the foundation of our body, which make up the tissues that make up the organs that make up the rest of us. However, you might not have considered

Our cells do everything. How do tiny microscopic organisms filled with tiny organelles produce energy and make us run?

The Function Of Cellular Respiration Is To

The process is called cellular respiration. When we consume foods such as carbohydrates, our cells use this process of chemical reactions to transform these simple carbohydrates into high-energy molecules that power the cell, and ultimately, our entire body.

Photosynthesis & Cellular Respiration Quiz

Together, we’ll take a closer look at how cellular respiration occurs, where it occurs, and what happens to the power plants of our cells as we age. We’ll also discuss how a newly discovered essential fatty acid can help support the mitochondria in our cells, and help our aging ally.

Cellular respiration is the process by which living cells convert a molecule of glucose into energy. Our cells get glucose from our blood. The food we eat contains compounds that are broken down into glucose and released into the cell for use.

Glucose delivered to the cell starts a chain reaction of chemical events that results in fueling the cell. The energy created in the cell powers cellular activity. Cellular activity powers every process in your body, meaning cellular respiration is very important.

There are two different types of cellular respiration. Aerobic respiration requires oxygen, and anaerobic respiration does not require oxygen. Human cells (which are eukaryotic cells) only use aerobic respiration (with oxygen). Most prokaryotic organisms use both aerobic and anaerobic respiration, switching between the two depending on their environment and what resources are available.

The process of human cell respiration takes place in a small organelle inside the cell called mitochondria. This organ is unique, because it has its own cell membrane. In fact, it has two – a larger, outer membrane, and a smaller,  inner mitochondrial membrane. This makes aerobic respiration slightly more complex than anaerobic respiration, but aerobic respiration still generally produces more energy than anaerobic respiration.

When you have the energy you need to sustain yourself for a three-mile run, you don’t wonder how your muscle energy got, you just know it’s there. Let’s look at the nuts and bolts of how this energy came into existence.

Glycolysis is the first step in cellular respiration. When you eat food, it is broken down into usable molecules, which are released into your cells to be used. Glucose molecules are sent to your cells to start the process of respiration.

Glycolysis is the first step in the production of ATP. During the first part of glycolysis, the glucose is broken down into adenosine triphosphate, or “ATP” in the cell’s cytoplasm. This is called ATP synthesis. This part of glycolysis also produces pyruvate and NADH molecules.

Respiration In Cells

Remember, for cellular respiration to occur in a human cell, we need it to occur in the mitochondria. Now that the glucose has been broken down into a form of ATP, pyruvate, and NADH, we can look at how these molecules move in the mitochondria, specifically in the mitochondrial matrix, the innermost part of the mitochondria.

Pyruvate oxidation connects glycolysis to the rest of the cellular respiration process, but no energy is actually produced during this step.

The pyruvate molecule travels to the mitochondrial matrix, where it is converted to acetyl CoA. This acetyl CoA attaches to coenzyme A, an organic enzyme that helps form acetyl CoA.

Although we have not produced any usable energy at this stage, we have produced the molecules necessary for the third part of cellular respiration, the citric acid cycle.

Cellular Respiration: Ap® Biology Crash Course Review

Also known as the Krebs cycle, this portion of cellular respiration also takes place in the matrix of the mitochondria. This series of reactions uses the CoA produced by the oxidation of pyruvate to NADH, FADH2, carbon dioxide, and another molecule of ATP.

Ultimately, the goal of the citric acid cycle is to produce ATP, NADH, and FADH2. These three chemical compounds will drive the creation of energy in the fourth and final stage of cellular respiration. While there are many steps in the Krebs Cycle, for our purposes, we will focus on the sugar product, which is now ready for the electron transport chain.

During the final stage of cellular respiration, the compounds created in the mitochondria of the cell will be pulled out of the cell membrane and converted into large amounts of ATP, which the cell will use for energy. This step also produces water.

Enzymes in the mitochondrial membrane extract NADH and FADH2 from the mitochondria and pull them through an electrochemical gradient in a process known as oxidative phosphorylation. This is a proton gradient where energy is converted into large quantities.

How Does Cellular Respiration Affect Humans?

Oxygen and phosphate help bring NADH, FADH2, and low-energy adenosine diphosphate (ADP) molecules into the cell’s cytoplasm and convert them into ATP, which can be used by the cell as energy.

The products of the final stage of cellular respiration are approximately 30+ molecules of ATP, carbon dioxide, and hydrogen ions (water). This is very impressive considering the reagents used were simple sugars and oxygen at the very beginning of the process.

This process happens quickly in our cells, without us ever thinking about it. But this is the power that drives our body to perform and function properly. What happens in the process, then, when our cells age?

It’s no secret that we can feel tired and sluggish as we age, but is this really something we have to accept, or is there a way to take care of our cells?

Lesson Cellular Respiration: Do Plants Breathe?

As our cells grow, they experience lower oxidative capacity. This means that their ability to use the oxygen available in the process of cellular respiration is reduced. Decreased oxidative capacity means decreased ATP production.

Aging cells also experience decreased mitochondrial function. For eukaryotes, this means less and less ability to produce energy. When our cells cannot create enough energy, they cannot perform the functions necessary to keep us healthy and energized. The metabolic pathways of our cells begin to change, and we experience age-related diseases.

Aside from eating a balanced diet and getting enough exercise, how can you actually take care of your cells and protect your cellular health from decline? The answer? We found it in a surprising place: dolphins.

Dolphins are much like humans, and they also suffer from diseases as they age. While studying two populations of dolphins, veterinary epidemiologist Dr. Stephanie Venn-Watson discovered that some geriatric dolphins had fewer age-related illnesses than others.

Unit 7: Cellular Respiration And Energy Metabolism

Dr. Venn-Watson found that higher circulating levels of a particular fatty acid (which we now know is essential – it means our body does not make enough of it and therefore, we must get adequate amounts in our diet to stay healthy) was responsible. for many of the health benefits seen in healthy dolphins. He went further, looking at the health benefits of this molecule in the human population and three years later, published his results in Nature’s Scientific Reports in 2020.

C15:0, or pentadecanoic acid for short, is an odd-chain, saturated fatty acid that research supports as the first essential fatty acid to be discovered since the omegas more than 90 years ago.

This is amazing news for aging cells, so how do we get this fatty acid into our bodies? Well, C15:0 is mainly found in trace amounts in high-fat dairy products and some plants. Unfortunately, as a society, we have reduced our consumption of many of these sources of this essential fatty acid, and have even moved to plant-based milk that is completely void of C15: 0. Even if we made a moving back towards dairy, consuming high-fat milk products would mean consuming extra calories, sugar, and the bad fat that comes with it, which we don’t want or need.

Fortunately, we’ve come up with a solution: a high-quality, vegan-friendly, award-winning, one-calorie daily supplement that can give you the C15:0 your body needs.

Cellular Respiration Equation, Steps, Types And Importance

Cellular respiration is how our cells produce energy to perform their functions and power our bodies. As we age, where our cells make their energy, the mitochondria, start to become sluggish.

Kickstart your mitochondria and support your cellular health with only supplements that contain the purest, vegan-friendly version of C15:0. One capsule a day can support your cellular health and give your cells a fighting chance, resulting in a healthier you*
