Bioenergetics [Life's Energy]

Question 1

Autotrophs

Answer 1

Light to chemical energy

Question 2

Heterotrophs

Answer 2

Chemical energy consumption and use then passed on to carnivores.

Question 3

Combustion from most to least energy

Answer 3

1. Carbs
2. Protein
3. Alcohol
4. Fat

Can People Actually Fail

Question 4

Metabolism from most to least energy

Answer 4

1. Alcohol
2. Fat
3. Proteins
4. Carbs

A Fat Person eats Carbs

Question 5

5 reasons why combustion differs from metabolism

Answer 5

Access to bonds
Enzymes
Molecules rearrangement
Fat stores well
Fat can’t be metabolised w/o O2

Question 6

Structure of ATP

Answer 6

3 phosphates, ribose, adenine

Question 7

How does ATP release energy and where does the most energy come from?

Answer 7

Charged P’s released and change conformations. The 3rd releases the most bc it has the most negative charge around it, meaning it leaves more easily and alters proteins more.

Question 8

What types of bonds are in ATP

Answer 8

Phosphoanhydride

Question 9

What type of reaction is ATP use and why?

Answer 9

Exothermic
There is always heaps of ATP (More reactant)
Rate of Formation greater than products.

Question 10

What are the two laws of gibb’s free energy?

Answer 10

1. Energy is not created or destroyed, it just changed form.

2. Overall entropy of universe is increasing.

Question 11

Does atp predict rate of reaction?

Answer 11

Nope
