5.3 Cellular Respiration

Question 1

What is the order of stages in cellular respiration?

Answer 1

1. Glycolysis 2. The link reaction 3. Krebs cycle 4. Electron transport chain

Question 2

What are the inputs of glycolysis?

Answer 2

Glucose, ADP, and NAD+

Question 3

What are the outputs of glycolysis?

Answer 3

Pyruvate, ATP, and NADH

Question 4

Where are the link reaction, the Krebs cycle, and election transport chain in the cell?

Answer 4

The mitochondria

Question 5

Where does glycolysis occur?

Answer 5

The cytoplasm

Question 6

What is the overall chemical equation for cellular respiration?

Answer 6

glucose + oxygen yields carbon dioxide + water

Question 7

What cellular process can happen in the presence of oxygen vs. with the absence of oxygen?

Answer 7

In the presence of oxygen the Krebs cycle, electron transport chain, and glycolysis can happen, in the absence of oxygen only glycolysis can occur.

Question 8

How many ATP molecules does glycolysis produce in the presence of oxygen?

Answer 8

2

Question 9

How many ATP molecules does the electron transport chain produce in the presence of oxygen?

Answer 9

around 30
