7.4 Study Guide

Question 1

Name the order of stages in cellular respiration:

Answer 1

1: Glycolysis
2: Link Reaction
3: Krebs Cycle
4: Electron Transport Chain

Question 2

Inputs and Outputs of each stage:

Answer 2

Glycolysis: ADP and Glucose; ATP
Krebs Cycle: ADP; ATP and CO2
Electron Transport Chain: O2 and ADP; H2O and ATP

Question 3

Where are the cycles located?

Answer 3

Glycolysis: Cytoplasm
Krebs Cycle: Mitochondria, matrix, membrane
Electron Transport Chain: Mitochondria, inter membrane

Question 4

What is the overall chemical equation for cellular respiration?

Answer 4

C6H12O6 + 6O2 To 6CO2 + 6 H2O
~29 ADP + ~29 P To ~29 ATP + ~29 H2O

Question 5

What are similarities between cells with or without oxygen?

Answer 5

Anaerobic Respiration
Uses Pyruvate
Regenerates NAD+
No ATP generated

Question 6

What are differences between cells with or without oxygen?

Answer 6

Different products
Completed by different things
Ability to reverse

Question 7

Why does the structure of the mitochondria increase ATP production?

Answer 7

The structure allows the creation of a high and low concentration area and the structure creates an in and out for the ions entering the mitochondria.
