Which Part Of Cellular Respiration Produces The Most Atp Molecules – You know that cells are the foundation of our bodies, making up the tissues that make up the organs that make up the rest of us. However, you may not have thought

Our cells do everything. How do tiny, microscopic organisms full of smaller organelles produce energy and keep us running?

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

Electron Transport Chain And Energy Production

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 us turn aging into an ally.

Cellular respiration is the process by which living cells convert a molecule of glucose into energy. Our cells get glucose from our bloodstream. The foods we eat contain compounds that are broken down into glucose and delivered to the cell for use.

Glucose delivered to the cell starts a chain reaction of chemical events that results in the cell functioning. The energy created in the cell fuels cellular activity. Cellular activity powers every process in your body, meaning cellular respiration is pretty 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) use only 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.

Aerobic Cellular Respiration

The process of human cell respiration takes place inside a small organelle inside the cell called a mitochondrion. 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. Which makes aerobic respiration more complex than anaerobic respiration, but aerobic respiration generally still produces more energy than anaerobic.

When you have the strength you need to sustain yourself for a three-mile run, you won’t wonder how the energy in your muscles has turned out, you just know it’s there. Let’s look at the nuts and bolts of how that energy came about.

Glycolysis is the first step in cellular respiration. When you eat food, it is broken down into small, usable molecular packages that are delivered to your cells for their use. Glucose molecules are sent to your cells to start the process of respiration.

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

Which Statement Is True Of Aerobic And Anaerobic

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

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

Pyruvate molecules travel 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 in this step, we have produced the molecules required for the third part of cellular respiration, the citric acid cycle.

Cellular Respiration Review

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

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

In the final phase of cellular respiration, compounds created within the cell’s mitochondria are pulled out of the cell membrane and converted into a mass amount of ATP, which the cell uses for energy. This stage also produces water.

Enzymes in the mitochondria membrane take NADH and FADH2 from the mitochondria and pull them down an electrochemical gradient in a process known as oxidative phosphorylation. It is a proton gradient where energy is converted into large amounts.

Chapter 19: Cellular Respiration

Oxygen and phosphate help bring NADH, FADH2, and low-energy adenosine diphosphate (ADP) molecules into the cell’s cytoplasm and convert them to ATP, which is available for the cell as energy.

The products of the final stage of cellular respiration are about 30+ molecules of ATP, carbon dioxide, and hydrogen ions (water). That’s pretty impressive considering the reactants used were simply sugar and oxygen at the very beginning of the process.

This process happens quickly in our cells, without us even thinking about it. But it is the power that drives our bodies 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 proactively take care of our cells?

Cellular Respiration: What Is It, Its Purpose, And More

As our cells age, they experience a decrease in oxidative capacity. This means that their ability to use available oxygen in the process of cellular respiration decreases. A decrease in oxidative capacity means a decrease in ATP production.

Aging cells also experience a decline in mitochondrial function. For eukaryotes, that means less energy-producing ability. When our cells don’t produce enough energy, they can’t perform the functions necessary to keep us healthy and energetic. The metabolic pathways of our cells begin to change, and we experience age-related disease.

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

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

Dr. found out Venn-Watson that the higher circulating levels of a particular fatty acid (which we now know is essential – meaning our body does not get enough of it and therefore, we must get sufficient amounts from our diet to stay healthy) for many of the health benefits seen in the healthiest dolphins. He continued, looking at the health benefits of this molecule in human populations and three years later, his findings were published in Nature’s Scientific Reports in 2020.

C15:0, or pentadecanoic acid for short, is an odd-chain, saturated fatty acid that is supported by research as the first essential fatty acid discovered since omegas over 90 years ago.

That’s fantastic news for aging cells, so how do we get this fatty acid into our bodies? Well, C15:0 is usually found in trace amounts in whole-fat dairy products and some plants. Unfortunately, as a society, we have reduced our intake of many of these sources of essential fatty acids, and have even switched to plant-based milks that are completely free of C15:0. Even if we go back to dairy, consuming whole-fat milk products means consuming extra calories, sugars, and bad fats that come with it, which we neither want nor need.

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