7.4 Study Guide

Question 1

The order of stages in cellular respiration

Answer 1

1. Glycolysis
2. Link Reaction Chain
3. Krebs Cycle
4. Etc

Question 2

The inputs and outputs of each stage

Answer 2

Glycolysis- Input glucose output pyruvate
Link Reaction-Inputs Pyruvate Outputs are CO2 and NADH
Krebs Cycle-Inputs NAD+ and water outputs are ATP and Carbon dioxide
ETC- Inputs NADH and oxygen outputs are ATP water, and NAD+

Question 3

The location of each stage

Answer 3

Glycolysis-In cyptoplasm
Link Reaction- Mitocondria
Kreb cycle- Matrix
ETC- Inner membrane

Question 4

The overall chemical equation for cellular respiration

Answer 4

Glucose+Oxygen: Carbon dioxide+Water

Question 5

Compare and contrast what happens in your cells to generate ATP when you have oxygen vs. no oxygen

Answer 5

With the presence of oxygen Glycolysis produces 2 ATP
Krebs cycle produces 2 ATP
ETC produces 30 ATP
With the absence
Glycolysis produces 2 ATP
Fermentation No ATP
