Answer 8

450 ATP

Question 9

Aerobic (…..) glycolysis uses __ and __ for energy production.

Answer 9

slow glycolysis;
muscle glycogen and blood glucose for energy

Question 10

Aerobic lipolysis uses ….. and ….. for energy production

Answer 10

uses muscle TG and
blood FFA for energy production

Question 11

In the Krebs Cycle:

1. Pyruvate is converted into ___ which forms ____.
2. Then acetyl-CoA combines with ___ to form ___ which also produces
3. The product produces ___molecules and ___
4. Then ___ molecule is made which turns into ____.

Answer 11

acetyl-CoA; Co2

oxaloacetate; citrate; Co2

three molecules of NADH; one FADH2

GTP; ATP

Question 12

……

Question 13

Pyruvate; triglicoriod and aacetyl-CoA can be broken down by the

Answer 13

Citric acid cycle

Question 14

What Process breaks down fatty acids into acetyl-CoA?

Answer 14

Beta-oxidation

Question 15

What is the Eclectron Transport Chain?
What does it do and Where?

Answer 15

Oxidative phosphorylation occurs in the mitochondria;

Electrons removed from NADH and FADH are passed along a series of carriers (cytochromes) to produce ATP

Question 16

1 NADH produces __ ATP
1 FADH produces __ ATP

Answer 16

2.5; 1.5

Question 17

Chemiosmotic hypothesis

Answer 17

H+ from NADH and FADH is combined with O2 to form water and ATP;

Gradant that moves electrons
Exygens final elevtron acceptor
It creates water and ATP

Hydrogen + Oxygen = Water and ATP

Question 18

Chemiosmotic hypothesis of ATP formation

Answer 18

Electron transport chain results in pumping of H+ ions across inner mitochondrial membrane

electrochemical gradient

Protons drive the transport

Question 19

How many Aerobic ATP can you get from one glucose Molecule?

Answer 19

32 Total ATP

Question 20

For each glucose you get _ pyruate

Answer 20

2

Question 21

Which gets more electrons? NADH or FADH?
Why?

Answer 21

You get more NAHD than FADH

Question 22

One mole of ATP has energy yield of _ kcal;

__ of ATP are formed from one mole of glucose

Potential energy released from one mole of glucose is __ kcal/mole

Answer 22

7.3 kcal;

32 moles;

686kcal

Question 23

Are we efficent with heat/OxidativePhosporylation?
.
Effeciency of aerobic respoiration is __% efficent

___ % of energy released as heat

Answer 23

34%;
66%

We need the heat to keep body temp consistant

Question 24

Hydraulic model of oxidative phosphorylation – rest vs. At exercise

Question 25

What factors of exercise use anaerobic and aerobic systems?

Answer 25

Anaerobic:
—Short-term,
—High intenisty exercoise

	Aerobic 
	—Long term 
	—Low to Moderate Intenisty. exercise
