Lesson 7.4

Question 1

What is cellular respiration?

Answer 1

A metabolic process that breaks down glucose and produces ATP so energy is usable for cells.

Question 2

What is the chemical equation for CR?

Answer 2

ADP+Glucose + Oxygen > CO2 + water + ATP

Question 3

What is the order of stages in cellular respiration?

Answer 3

1. Glycolysis
2. Link Reaction
3. Kerbs Cycle
4. Electron Transport Chain

Question 4

Describe the inputs and outputs and location of glycolysis.

Answer 4

Inputs : Glucose , ADP (x2), NAD+(x2)
Outputs : pyruvate (x2), ATP (x2), NADH (x2)
Location: Cytoplasm of cell

Question 5

Describe the inputs and outputs and the location of the link reaction.

Answer 5

Inputs: pyruvate (x2), NAD+(x2), coenzyme A(x2)
Outputs : Acetyl-CoA (x2), NADH(x2), CO2 (x2)
Location: Mitochondrion

Question 6

Describe the inputs and outputs and the location of the Kerbs cycle.

Answer 6

Inputs : Acetyl-CoA (x2), FAD (x1), NAD+(x3), ADP(x1)
Outputs : Co2 (x4), ATP, NADH (x6), FADH (x2)
Location: Mitochondria

Question 7

Describe the inputs and outputs and the location of the ETC.

Answer 7

Inputs: NADH, FADH, ADP, Oxygen
Outputs: NAD+, FAD, water, ATP (x30)
Location :

Question 8

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

Answer 8

When you have oxygen in your cells, aerobic respiration happens with all 4 stages and produces around 34-38 ATP. When you have no oxygen in your cells, anaerobic respiration occurs with glycolysis and fermentation only and produces 2 ATP/glucose.
