Cell Respiration PowerPoint Notes

Flashcards covering key vocabulary and concepts related to cell respiration, photosynthesis, and glycolysis.

Metabolism

The combination of chemical reactions an organism undergoes to build up or break down materials.

Cellular Respiration

The process that releases energy from food.

Relationship Between Photosynthesis and Cellular Respiration

The products of photosynthesis are the reactants of cellular respiration, and vice versa.

Cell Respiration Equation

C6H12O6 + 6O2 -> 6H2O + 6CO2 + energy (ATP)

Photosynthesis Equation

6CO2 + 6H2O + sunlight -> 6O2 + C6H12O6

Aerobic Respiration

Occurs when oxygen is available.

Anaerobic Respiration

Occurs when oxygen is NOT available; yeast is an example. Can make lactic acid in our body.

Cell Respiration Main Stages

Glycolysis, Krebs Cycle, Electron Transport Chain.

Glycolysis

Doesn't require oxygen (anaerobic); occurs in the cytoplasm of your cells.

Glycolysis

All respiration begins with this process.

Glycolysis

During this process, glucose is broken down into pyruvic acid.

Energy in Pyruvic Acid

About 90% of the energy available in one glucose molecule is still unused and locked in the chemical bonds of pyruvic acid.

Net Gain of ATP in Glycolysis

2 ATP
