The approach most commonly used to measure metabolic rate is to measure the rate of O2 consumption. Although there are small errors inherent in this method, it is easy, and provides a good estimate of metabolic rate. Why is the rate of oxygen consumption an appropriate measure of metabolic rate?

Metabolic rate is the amount of energy used per unit time. The production of usable energy in the form of ATP depends largely on aerobic respiration.

Metabolic rate is the amount of energy used per unit time. The hydrolysis of ATP to ADP and Pi is an aerobic process.

Metabolic rate is the amount of energy released in anabolic processes, and anabolic processes are aerobic.

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone
