All About Cellular Respiration

If you learn nothing from today, at least know these things:

• Cellular Respiration Equation:

  C₆H₁₂O₆ + 6O₂ -> ATP + 6H₂O + 6CO₂

Some General Information

1. All living things need energy to stay alive. So, all living things perform cellular respiration

2. Some molecules are too big to pass through the cell membrane, like Starch. Those molecules must be broken down into smaller, simpler ones, such as glucose, through digestion.

3. Next the glucose (or other simpler molecules) must be broken down further by the process of Cellular Respiration to release the energy stored in them

4. Cellular respiration involves a series of chemical reactions to accomplish this. These reactions are controlled by enzymes

5. In eukaryotic organisms, this Cellular Respiration occurs primarily in the mitochondria.

6. During cellular respiration, cells capture much of the energy that is released from glucose and use it to form new bonds in high-energy molecules of ATP

7. In many organisms, cellular respiration requires Oxygen, which must be brought into the organism from the environment.

8. Obtaining oxygen from the environment and releasing carbon dioxide (and water vapor) is called gas exchange

Why is it being broken down?

How does the Mitochondria Work, exactly?

The mitochondria is described as being a large, wrinkled, plastic bag inside a smaller unwrinkled plastic bag. Outer membrane is made out of a phospholipid bilayer (recall, it likely used to be a prokaryote billions of years ago!). The inner membrane is highly complex and have folds, which contain that enzyme we've been talking about, ATP Synthase.
hwbrjkbrjrejrkel
ATP Synthase synthesizes ATP from ADP by adding a phosphate group through the process of Dehydration Synthesis.

So, Anaerobic Respiration, you say 🤔

Aerobic respiration can't happen without oxygen, so a different set of reactions occur. We call it Anaerobic Respiration, or Fermentation for short. Fermentation leads to an incomplete breakdown of organic compounds due to the lack of oxygen.
ewjrngkm
This process is primarily done by prokaryotes (like Yeast), which makes CO2 and Ethyl Alcohol (ethanol), like in beer, mead, and wine.
Where do you think it occurs in those organisms?

Multiple Choice

Based on your knowledge of Biology: Where does anaerobic cellular respiration take place in prokaryotes?

• Chloroplast

• Stroma

• Mitochondria

• Cytoplasm

Multiple Choice

Another name for anaerobic cellular respiration is

• Fermentation

• Citric acid (Krebs) cycle

• Calvin cycle

• Conjugation

Multiple Choice

Fermentation is the ___ of organic compounds in the absence of oxygen.

• complete breakdown

• partial breakdown

• incomplete breakdown

• total breakdown

Can Fermentation happen in eukaryotes?

Yeah, and it's why your muscles can get sore. Fermentation in your muscle cells makes Lactic Acid. Lactic acid forms in your muscles when they are forced to operate without enough oxygen, such as during vigorous exercise. When lactic acid cannot be removed quickly enough, it builds up and your muscles get sore and tired.

Great video on lactic acid production and exercising :) ---->

Are there other things that make lactic acid?

Other organisms, such as bacteria can make lactic acid. Under the right conditions, the lactic acid formed by bacterial fermentation of milk produces foods such as cheese and yogurt. You can also make delicious pickles and soy sauce with it.

It is important to remember that fermentation (which produces either alcohol or lactic acid) releases no more ATP than the base anaerobic respiration. The energy that remains in the chemical bonds of alcohol or lactic acid is not used by the organism.
