AP Biology Photosynthesis and Cellular Respiration

Front

What is the equation for cellular respiration?

Back

6O₂ + C₆H₁₂O₆ → 6CO₂ + 6H₂O + Energy

Front

Where does the Krebs cycle occur?

Back

Mitochondrial matrix

Front

What is released as a by-product of photosynthesis?

Back

Oxygen, which is a direct by-product of splitting water molecules.

Front

Where does the Electron Transport Chain (ETC) occur?

Back

Inner mitochondrial membrane

Front

What happens during the light reactions of photosynthesis?

Back

Light is absorbed and funneled to reaction-center chlorophyll a.

Front

What is photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of NADP+ in photosynthesis?

Back

NADP+ acts as an electron carrier, becoming reduced to NADPH during the light reactions.

Front

What is the main purpose of the Krebs cycle?

Back

To produce electron carriers (NADH and FADH₂) and ATP through the oxidation of acetyl-CoA.

Front

What is chemiosmosis?

Back

The movement of ions across a selectively permeable membrane, down their electrochemical gradient, which is used to generate ATP.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, and converts it into chemical energy.
