It produces carbon dioxide, water, and ATP (usable energy)

6O2 + C6H12O6 ---> 6CO2 + 6H2O + 36ATP
Photosynthesis and Cellular Respiration are complimentary processes.

Photosynthesis removes carbon dioxide from the air and cellular respiration puts it back.

Photosynthesis releases oxygen into the atmosphere and cellular respiration uses oxygen to release energy from the food.

The organelle important in cellular respiration is the mitochondrion.

The internal membrane has many folds and turns that increase the surface area of the membrane.

The space between the inner and outer membrane is called the INTERMEMBRANE SPACE.

The space inside the inner membrane is called the MATRIX.

Remember: Glucose stores energy and ATP is the usable form of energy for the cell, so the energy in glucose must be transferred to ATP.
Breaking down glucose all at once would burn up the cell; therefore glucose must be broken down in steps.

Glycolysis occurs in the cytoplasm.

From here there are two possible paths depending on whether there is oxygen available or not.

If oxygen is present, the process will be aerobic.

If oxygen is not present, the process is anaerobic.

The energy in the pyruvic acids is used to make ATP from ADP, there are two stages to this:
Using oxygen, enzymes in the KREBs CYCLE break down pyruvic acid to form 3 carbon dioxide molecules, 2 ATP, and high-energy electron carriers.
This occurs in the matrix of the mitochondria.

Uses high-energy electron carriers to convert ADP into ATP. This occurs in the inner membrane of the Mitochondria.

Fermentation: allows glycolysis to continue producing ATP even if there is no oxygen present.

Different organisms have different end products of fermentation.
Lactic Acid Fermentation

- occurs in animal, bacterial, and fungal cells.
- converts pyruvic acid into lactic acid.
The process in bacterial and fungi is used in the production of yogurt and cheeses

When lactic acid builds up in muscle cells it causes burning a fatigue.

In us it results in being sore after a hard aerobic workout.

Alcoholic Fermentation

occurs in yeast and plant cells.

converts pyruvic acid in ethyl alcohol and carbon dioxide.

This process is used in the production of alcoholic beverages and rising breads (carbon dioxide bubbles make yeast breads rise.)
