What is the role of coenzyme a?
a) it gets broken down to make atp
b) it gets attached to a two carbon molecule
c) it is an enzyme that breaks down pyruvate
d) it is an enzyme that will break down acetyl
e) none of the above

B) It gets attached to a two carbon molecule

Explanation:

Oxidative decarboxylation of pyruvate in the mitochondrial matrix produces two carbon molecule. This two carbon molecule is attached to CoA and acetyl CoA is formed. Coenzyme A (CoA) gets attached to the acetyl group via its thiol group and serves as acyl carrier for the first reaction of Kreb's cycle.

The acetyl CoA then enters the Kreb's cycle and is completely broken down into CO2 and H2O.

answer; i believe the correct answer is (a)0

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
