biology 110 chapter 5

Where within the cell is ATP produced?

mitochondria

Which of the following shows the flow of energy through the biosphere, to cellular level?

solar energy - chloroplast - mitochondria

Which of the following is not a type of potential energy?

the energy of a ball rolling down a hill

Once the substrate moves into the active site of the enzyme,

the enzyme alters in shape to more closely fit the substrate.

The part of the enzyme into which the substrate fits is called the

active site.

Identify which of the following statements is NOT true. - about ATP

ATP is comprised of a sugar, base, and two phosphate groups.

Which of the following statements most accurately describes the first law of thermodynamics?

Energy can neither be created nor destroyed, but it can be changed from one form to another.

Simple diffusion across a plasma membrane is called passive transport because it

does not require energy from the cell.

When neurons release their neurotransmitters, they release them by secretory vesicles fusing with the plasma membrane thereby emptying their contents into an area that can stimulate some response. What type of cellular transport is occurring as the vesicle forms and then surfaces on the cell's plasma membrane?

exocytosis

Enzymes are able to speed up the rate of a reaction by

lowering the energy needed for the reaction to proceed.
