Unit 5 Study Guide: Cellular Energy

Front

What is the relationship between the photosynthesis equation and cellular respiration equation?

Back

These reactions are inverses of each other.

Front

What is broken into pyruvate during glycolysis?

Back

Glucose is broken into pyruvate during glycolysis.

Front

What pigment do most plants use to absorb light energy?

Back

Chlorophyll.

Front

What happens to NADP+ and NAD+ in photosynthesis and cellular respiration?

Back

NADP+ becomes NADPH used in photosynthesis; NAD+ becomes NADH and FAD+ becomes FADH2 used in cellular respiration.

Front

Where does the Krebs cycle take place?

Back

In the matrix of the mitochondria.

Front

How much CO2 is formed per pyruvate in the Krebs cycle?

Back

2 CO2 are formed per pyruvate.

Front

What are the ATP, NADH, and FADH2 yields per pyruvate in the Krebs cycle?

Back

1 ATP, 3 NADH, and 1 FADH2 per pyruvate.

Front

What is the total yield of ATP, NADH, and FADH2 per glucose in the Krebs cycle?

Back

Double the amounts per pyruvate: 2 ATP, 6 NADH, and 2 FADH2.

Front

What is glycolysis?

Back

The process of breaking down glucose into pyruvate.

Front

What is the role of chlorophyll in photosynthesis?

Back

To absorb light energy and transfer it to electrons.
