5.3 Study Guide

Question 1

Order of stages in cellular respiration

Answer 1

Gycolysis, the Kerbs cycle, and the electron transport chain

Question 2

Inputs and outputs of each stage

Answer 2

Inputs -glucose and oxygen
Outputs - carbon dioxide, water, and ATP (energy)

Question 3

Location of each stage

Answer 3

Glycosis - cytsol of the cytoplasm
Kerbs cycle - in the matrix (occurs in the mitochondria)
Electron transport chain - inner membrane of the mitochondrion

Question 4

Overall chemical equation for cellular repiration

Answer 4

C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + ATP

Question 5

Compare and contrast what happens in your cells to generate ATP when you have oxygen

Answer 5

In our cells, oxygen allows cellular respiration to proceed. It works best with oxygen. With oxygen, organisms can break down glucose all the way to carbon dioxide

Question 6

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

Answer 6

Without oxygen, organisms can split glucose into just two molecules of pyruvate and much less ATP would be produced
