What Is The Overall Purpose Of Cellular Respiration – You know that cells are the foundation of our body, forming the tissues that make up the rest of our organs. However, you might not consider it

Our cells do it all. How do tiny, microscopic organisms full of even tinier organs generate energy and drive us?

What Is The Overall Purpose Of Cellular Respiration

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

Together, we’ll take a closer look at how cellular respiration occurs, where it occurs, and what happens to our cells’ power plants as we age. We discuss how a newly discovered essential fatty acid supports the mitochondria in our cells and helps make aging our 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 food we eat contains compounds that are broken down into glucose and delivered to the cell for use.

Glucose delivered to the cell initiates a chain of chemical events that result in the cell being energized. Energy created in the cell stimulates cellular activity. Cellular activity powers every process in your body, which means 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 (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 available resources.

Overview Of Photosynthesis

The respiration process of a human cell takes place inside a tiny organelle inside the cell called a mitochondrion. This organ is unique in that 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 generally produces more energy than anaerobic respiration.

When you have the energy to sustain yourself for a three-mile run, you don’t wonder how the strength in your muscles got there, you know it’s there. Let’s take a look at the nuts and bolts of how that power came into existence.

Glycolysis is the first step in cellular respiration. When you eat food it is broken down into smaller, usable molecule packets and delivered to your cells for 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 cell’s cytoplasm. This is called ATP synthesis. This part of glycolysis also produces molecules of pyruvate and NADH.

Turn Problems Into Opportunities: Photorespiration For Improved Plant Metabolism

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

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

Molecules of pyruvate travel to the mitochondrial matrix, where it is converted to acetyl CoA. This acetyl CoA is attached to coenzyme A, an organically occurring 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: Glycolysis, Krebs Cycle, Electron Transport (us Edition)

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

Ultimately, the purpose of the citric acid cycle is to produce ATP, NADH, and FADH2. These three chemical compounds drive the creation of energy in the fourth and final step of cellular respiration. Although there are several 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 step of cellular respiration, compounds created inside the cell’s mitochondria are pulled out of the cell membrane and converted into a mass of ATP, which the cell then uses for energy. This phase also produces water.

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

Aerobic Respiration Definition, Diagram, And Steps

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

The end products of cellular respiration are about 30+ molecules of ATP, carbon dioxide, and hydrogen ions (water). That’s pretty impressive considering the reactants used simple sugars and oxygen at the start of the process.

This process happens quickly in our cells, without us even thinking about it. But it is the force that motivates our body to maintain and function properly. What happens to the process when our cells age?

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

Cellular Respiration: The Electron Transport Chain

As our cells age, they experience less oxidative capacity. This means that the ability to use available oxygen in the process of cellular respiration is reduced. Reduced oxidative capacity means reduced ATP production.

Aging cells have reduced mitochondrial function. For eukaryotes, that means less and less energy-producing capacity. When our cells can’t generate 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 ailments.

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

Dolphins are like humans and get sick as they get older. While studying two populations of dolphins, veterinary epidemiologist Dr. Stephanie Wen-Watson found that some geriatric dolphins had fewer age-related diseases than others.

Dr. Wen-Watson discovered that high circulating levels of a certain fatty acid (which we now know is essential – meaning our bodies don’t make enough of it and therefore, we need to get enough of it from our diet to stay healthy) is the cause. For the many health benefits found in healthy dolphins. He went further, examining the health benefits of this molecule in the human population and published his findings three years later, in 2020, in Nature’s Scientific Reports.

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

This is great news for aging cells, so how do we get this fatty acid into our bodies? Well, C15:0 is mostly found in trace amounts in whole-fat dairy products and some plants. Unfortunately, as a society, we have reduced our intake of these sources of this essential fatty acid and switched to plant-based milks that are completely devoid of C15:0. Even though we’ve turned back to dairy, consuming full-fat dairy products means consuming extra calories, sugars, and bad fats that we don’t want or need.

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

Cellular Respiration: Glycolysis

Cellular respiration is how our cells produce energy to perform their functions and power our bodies. As we age, the mitochondria, where our cells produce their energy, begin to slow down.

Kickstart your mitochondria and support your cellular health with the only supplement that contains a pure, vegan-friendly version of C15:0. Just one capsule a day supports your cellular health and gives your cells a fighting chance, resulting in you feeling healthier*

Getting older is a privilege, but if you suffer from age-related ailments, it may not feel like it. There is currently a large research focus on what causes aging and what steps we can take to slow the process.
