How does ATP relate to membrane transport?a. The movement of a substance down its concentration gradientthrough transport proteins requires the hydrolysis of ATP.b. The higher the concentration of ATP in the cell, the more permeablethe membrane is to water and small, nonpolar molecules.d. A cell uses the energy in ATP to transport substances against theirconcentration gradient.c. Digestion produces a high concentration of ATP outside the cell,and the ATP enters the cell via facilitated diffusion.

Na+ moves from high to low concentration, across the plasma membrane, through a protein channel that is permenantly open. Which statement is true about this process? a. It does not require ATP b. It is a form of active transport c. Movement is against the concentration gradient of Na+ d. The channel probably allows many different molecules and ions to cross

Where will the energy for active transport be derived from? A. Hydrolysis of ATP B. Co-transport of metabolites via carrier molecules, channels or gates C. Amino acid rearrangement due to conformational changes in the protein carriers, channels or gates. D. Both A and B E. All of these
