Chapter 7

Question 1

Cellular respiration

Answer 1

How living cells obtain energy from organic molecules

Question 2

4 metabolic pathways

Answer 2

Glycolysis
Breakdown of Pyruvate
Citric acid cycle
Oxidative phosphorylation

Question 3

Glycolysis

Answer 3

Break down of glucose sugar
In cytosol
Stage 1

Question 4

phases in glycolysis?

Answer 4

1 energy investment
2 cleavage
3 energy liberation

Question 5

Energy investment

Answer 5

2 ATP added to crest fructose
Step 1-3

Question 6

Cleavage

Answer 6

6 carbon molecule broken in to 2 carbon
Step 4-5

Question 7

Energy liberation

Answer 7

2 glyceraldehyde phosphate molecule broken broken down into putrivate
Produces 2 NADH & 4 ATP
Step 6-10

Question 8

What is stage2?

Answer 8

Breakdown of pyruvate to an acetal group

Question 9

Break down of pyruvate to an acetal group

Answer 9

In eukaryotes, pyrurate is transported to mitochondrial matrix
by pyruvate dehydrogenase
co2 removed from both pyruvate
1NADH made/ pyruvate

Question 10

Citric acid cycle

Answer 10

Stage 3
Metabolic cycle
a circulated process where acetal molecule enters in steep 1 & relics energy in steep 3,4,5,6,& 8
releases 2 CO2 molecule /pyruvate
1 ATP
3 NADH
1FADH2
** per pyruvate molecule
2 pyruvate/ glucose molecule **
** everything X 2*

Question 11

Stage 4

Answer 11

Oxidative phosphorylation
needs oxygen
High energy electrons removed from NADH & FADH2 to make ATP

Question 12

What stage involves electron transport chain

Answer 12

Stage 9: oxidative phosphorylation.

Question 13

Electron transport chain (ETC)

Answer 13

Group of protein complexes & small Organic molecules embedded in the inner mitochondrial membrane
