Question 6

How many ATPs are produced during fermentation

Answer 6

None

Question 7

Answer 7

Fermentation

Question 8

What do pigments do in plants and where are they found?

Answer 8

They capture light energy and they are found in chloroplasts

Question 9

What are the 2 light dependent reactions

Answer 9

ATP Synthesis from absorption of light energy and Photolysis

Question 10

What is a light independent reaction

Answer 10

CO2 Fixation

Question 11

Which group gets energy from light; carbon from carbon dioxide (Example: plants and green & purple sulfur bacteria)

Answer 11

Photoautotrophs

Question 12

Which group gets energy from light; carbon from organic molecules (Example: green and purple non-sulfur bacteria)

Answer 12

Photoheterotrophs

Question 13

Which group gets energy from inorganic compounds; carbon from carbon dioxide (Example: Nitrobacter)

Answer 13

Chemoautotrophs

Question 14

Which groups gets energy and carbon from organic molecules; many aerobic organisms

Answer 14

Chemoheterotrophs

Question 15

Includes many regulatory process that controls the metabolic rate of individual cells; Can be repression (inhibition) or induction (stimulation)

Answer 15

Metabolic Regulation

Question 16

This inhibitor binds enzyme at site other than active site; Changes enzyme’s shape so that it becomes less active

Answer 16

Noncompetitive Inhibitor

Question 17

What happens in non-competitive inhibition w/ an active form of an allosteric enzyme

Answer 17

The active site remains unchanged because the inhibitor is not bound to the regulatory site. The substrate can bind to the enzyme

Question 18

What happens in non-competitive inhibition w/ an inactive form of an allosteric enzyme

Answer 18

The inhibitor is bound to the regulatory site and the active site is then changed. The substrate can’t bind to the enzyme

Question 19

What catalyzes the slowest or rate-limiting reaction in the pathway

Answer 19

Pacemaker enzyme

Question 20

What are some coenzyme transports

Answer 20

ATP, NAD, NADP, FAD
