Some bio help please?

Question

1) Pyruvate is formed in the

1. mitochondria.

2. nucleus.

3. muscles.

4. cytoplasm.

2)Fermentation allows glycolysis to continue until there is no more glucose.

True

False

3)The reactions that “fix” carbon take place in photosystem II.

True

False

4) Plant cells use light energy to make ATP and NADPH.

True

False

5) The electrons from the splitting of water are carried into the Calvin cycle by ATP.

True

False

Answer 1

I disagree with ATP-man on a couple of points.

1) 4 cytoplasm

Pyruvate is formed in the cytoplasm, because that is where glycolysis occurs. Pyruvate is oxidized in the inner mitochondrial membrane.

2)True  

Fermentation can occur till all of the glucose is used up because it doesn't require oxygen.

3) False

The reactions that fix carbon takes place in the Calvin cycle and not with any photosystem.

4)True

Photosystem I helps make ATP and photosystem II helps make NADPH.

5) False

Electrons are carried to the Calvin cycle by NADPH. ATP is an energy carrier not an electron carrier.

Answer 2

1.  mitochondrion

2. true

3. false

4. true

5. false, The electrons do not go into the calvin cycle the ATP does all by itself.

Answer 3

1) 1

2) true

3)false

4) false
