Answer 1

Cellular Respiration

Question 2

____________
- Anabolic with regards to the carbon input
- Light energy input
- Uses NADPH as an electron carrier
- Generates ATP for the Calvin cycle
- Oxidation of electron carrier used to reduce a carbon-containing molecule
- A proton gradient is coupled to ATP synthesis
- Inputs are C02 and 1-420
- Outputs are triose phosphate and 02
- Electron transport chain coupled to proton pumping

Answer 2

Photosynthesis

Question 3

In a favorable chemical reaction, the reactants have more free energy / less free energy than products. In an unfavorable chemical reaction, the reactants have more free energy / less free energy than products.

Answer 3

More free energy, less free energy

Question 4

The energetically favorable / energetically
unfavorable conversion of NAD+ to NADH is coupled to the energetically
favorable / energetically unfavorable conversion of glucose to pyruvate.
Therefore, glucose has less free energy / more free energy than pyruvate.

Answer 4

Energetically unfavorable, energetically favorable, more free energy

Question 5

The energetically favorable / energetically
unfavorable conversion of NADH to NAD* is coupled to the energetically
favorable / energetically unfavorable conversion of pyruvate to lactic acid.
Therefore, pyruvate has less free energy / more free energy than lactic
acid.

Answer 5

Energetically favorable, energetically unfavorable, less free energy
