Question

1. We have learned that energy can exist in two primary forms: potential energy and kinetic energy a. Which of the two molecules below contains less potential energy? How do you know? (4 points) CH,OH CH OH —0 OH он H-C-H OH OH b. Glucose is high in potential energy. Why does the cell not simply use glucose to power cellular processes? (2 points) c. Explain how the hydrolysis of ATP can convert potential energy into kinetic energy. (4 points)

please answer each in 2-3 sentences. thank you

Answer 1

1.a.

Methane (CH4) contains less potential energy. This is because there are less bonds present in methane than in sugar molecule. More bonds breaking will release more energy in sugar.

b. ATP breakdown liberates just right amount to do any work. Where as glucose releases large amount of energy. Glucose alos has to pass through chain of reactions to liberate energy where as ATP releases small amount of energy in just one step.

c.ATP has 3 phosphate groups attached to it. The last phosphate gropu when removed releases more energy. The energy can be used to contract a muscle by pulling muscle proteins together hence decreasing the muscle size. The muscle when contracts can move hand or leg.
