please help me answer question 7 and 8

7.

Certain areas in Arizona, Nevada, California and Texas can have up to 4000 sunny hours a year. The fact that these vast lands are less populated and agriculturally not suitable makes them ideal for solar power plants. Though most commercial solar panels have efficiencies from 15% to 20%, researchers have now developed solar cells with efficiencies approaching 50%. If you are asked to plant a solar energy system in these areas using the newest technology, how much land do you

need to produce enough energy for the US.

Make the conservative assumptions that the average light energy landing to the Earth surface is 1.0 cal/(cm2 min).

An estimate for the US energy consumption by major sources is given below.

8. : The following table shows the glycolysis reactions and their standard Gibbs free energy changes at 25 C. Answer the following questions:

A. What is the Gibbs free energy expression of the glycolysis pathway?

B. What is the overall reaction of the glycolysis pathway?

C. Suppose that the physiological concentrations of some metabolites are known as follows:

micromolar Pyruvate 380 NADH 50 H+ 0.1 ATP ? Glucose 3000 NAD+ 540 ADP ? Pi 3500

What should be the ATP:ADP ratio so that the glycolysis proceeds spontaneously at 25 C?
