5.3 Study Guide

Question 1

The order of stages in cellular respiration

Answer 1

Glycolysis
the link reaction
the Krebs Cycle
ETC

Question 2

The inputs and outputs of each stage

Answer 2

Glycolysis-
Inputs: glucose, ADP, NAD
Outputs: pyruvate, ATP, NADH

the link reaction-
inputs: pyruvate, CoA, NAD
outputs: Acetyl CoA, CO2, NADH

the Krebs Cycle-
inputs: Acetyl CoA, ADP, NAD
outputs: CO2, ATP, NADH

ETC
Inputs- glucose and oxygen

Outputs- carbon dioxide, water, and ATP

Question 3

The location of each stage

Answer 3

glycolysis- cytoplasm
link reaction and Krebs cycle- mitochondria
ETC- the inner mitochondrial membrane

Question 4

The overall chemical equation for cellular respiration

Answer 4

glucose + oxygen -> carbon dioxide + water.

C6H12O6 + 6O2 –> 6CO2 + 6H2O + Chemical Energy

Question 5

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

Answer 5

oxygen- organisms can break down glucose all the way to carbon dioxide and resulting in over 30 ATP

no oxygen- mitochondrial ATP production is reduced to making 2 ATP.
