Lecture 7

Question 1

Anabolic Metabolism

Answer 1

Builds complex molecules from simpler ones

Question 2

Catabolic Metabolism

Answer 2

Breaks down complex molecules to form simpler ones.

Question 3

Exergonic reaction

Answer 3

doesn’t require energy input, spontaneous, produces energy, -G value

Question 4

Endergonic Reaction

Answer 4

Requires energy, non spontaneous

Question 5

____ of ATP releases energy

Answer 5

hydrolysis

Question 6

When is ATP regenerated?

Answer 6

Cellular respiration

Question 7

Enzyme active site process

Answer 7

1. Substrate enters active site
   2.held in place by weak interactions
2. active site lowers AE
3. substrates converted to products
4. products released
5. site open again

Question 8

Allosteric regulation

Answer 8

a molecule binds to a site on an enzyme to either activate or inhibit the enzymes function

Question 9

Increasing temp….

Answer 9

increases rate of reactions, too high temps deregulates proteins

Question 10

Which of the following is an exergonic reaction?
1 Formation of a peptide bond
2 Hydrolysis of ATP
3 Photosynthesis
4 Osmosis

Answer 10

2. Energy is released as a byproduct

Question 11

Which of the following is an example of an anabolic pathway?
1 Breaking down glucose into water and carbon dioxide to release energy
2 Digestion of proteins
3 Motor proteins moving along a microtubule
4 Synthesis of sugar molecules from carbon dioxide during photosynthesis

Answer 11

4, anabolic is making larger molecules from smaller ones
