Energy Process

Question 1

How many enzymes are in glycolysis?

Answer 1

11

Question 2

What do the enzymes/proteins do in glycolysis?

Answer 2

Break down glucose

Question 3

What is the end result from glycolysis?

Answer 3

Two different 3-Carbon molecules

Called PYRUVATE

Question 4

What two options does pyruvate have to do next?

Answer 4

Lactic acid (Anaerobic)
OR
Kreb’s Cycle (Aerobic)

Question 5

If glycolysis is happening at a fairly low rate, which process will most likely occur?

A) Lactic Acid
B) Kreb’s Cycle

Answer 5

B) Kreb’s Cycle

Question 6

If glycolysis is happening at a very high rate, which process will most likely occur?

A) Lactic Acid
B) Kreb’s Cycle

Answer 6

A) Lactic Acid

Question 7

What causes muscles to feel fatigue and burning when lactic acid process is occuring?

Answer 7

A strong acid is formed and liberates an H ion which messes up the proteins of actin & myosin. This causes a burning and fatigue sensation.

Question 8

Why can we keep using the lactic acid process if we feel fatigue and burning in the muscles?

Answer 8

The production of lactic acid allows more glucose to be processed through glycolysis. ATP created in the glycolysis allows the muscles to keep contracting.

Question 9

What can an accumulation of lactic acid create?

Answer 9

Pyruvic acid- which will simultaneously initiate the Kreb’s cycle

Question 10

What is the Kreb’s Cycle’s MAIN function?

A) Give the body energy
B) Produce CO2
C) Produce ATP

Answer 10

B) Produce CO2

Question 11

How many ATP is produced for every Kreb’s Cycle

Answer 11

2

Question 12

What two byproducts of the Kreb’s Cycle go to the Electron Transport Chain?

Answer 12

NADH + FADH

Question 13

Which organelle does ETC take place?

Answer 13

Mitochondria

Question 14

What byproduct does ETC create?

Answer 14

NAD because H+ has left.

& H2O

Question 15

Where does the NAD go that is created from the ETC?

Answer 15

Back to the Kreb’s Cycle

Question 16

Which produces the most ATP?

A) Kreb’s Cycle
B) Beta-Oxidation
C) Electron Transport Chain

Answer 16

C) ETC

Question 17

What is lipogenesis?

Answer 17

If we do not use the energy, liver rearranges the covalent bonds to fatty acids and they combine to make triglycerides.

Question 18

Can body use triglycerides for energy? If so, how?

Answer 18

Yes!
It breaks it down into 3 molecules and uses it for energy. 2 of which are CO2 and one is H2O

Question 19

What form of energy production do sports players use?

Answer 19

Glycolysis

Use carbs for energy

Question 20

How much time of energy do we get out of 1 ATP?

Answer 20

~3 seconds

Question 21

Is creatine stored in the body?

Answer 21

No

Question 22

What does it mean if someone has high creatine levels in the body?

Answer 22

Kidney is not working properly or muscles have damage

Question 23

Creatine has a _______ effect.

A) hydrating
B) dehydrating

Answer 23

B) dehydrating

Question 24

Per 1 glucose molecule, how much ATP is made from ETC

Answer 24

ETC nets 32 ATP/1 glucose molecule

Question 25

Calorie is a measurement of _____.

Answer 25

Heat

Question 26

When someone is in a calorie deficit, what enzyme does it suppress?

Answer 26

Lipase

Question 27

When lipase is suppressed, what happens?

Answer 27

The body will use fat for energy

Question 28

True/False: We can only eat if our tastebuds find the food pleasureable?

Answer 28

True

Question 29

Which organ uses fat the most?

Answer 29

Liver

Question 30

What happens on a keto diet?

Answer 30

Nervous system NEEDS carbs, so it finds another way to get them.

It uses beta-oxidation (to make Acetyl CoA).

Liver uses fat and combines it with Acetyl-CoA to make ketones.

Ketone goes to brain, after 2 weeks, the brain has developed enzymes to use ketones for energy

Question 31

If someone is losing more than 2/lb a week, what else are they losing besides fat?

Answer 31

Muscle mass

Question 32

What are the byproducts of Glycolysis?

Answer 32

2 ATP
2 NADH
2 Pyruvate

Question 33

What are the byproducts of Krebs Cycle?

Answer 33

2 ATP
2 CoA
2OH
6 CO2

Question 34

What are the byproducts of Beta oxidation

Answer 34

460 ATP total
