Which of the following transport mechanisms utilizes energy?
a. osmosis
b. endocytosis
c. diffusion
d. facilitated diffusion

The correct answer is B) Endocytosis.

Endocytosis can be defined as the uptake of large molecules by a cell that requires energy of the cell. Therefore, it is an energy consuming process.

Example- Ingestion of bacteria by macrophages is an energy consumig process and described under endocytosis.

On the other hand, osmosis ( diffusion of water), diffusion, and facilitated diffusion ( requiring carrier proteins) are all passive phenomenon that do not require energy.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
