Question

1)Describe two ways that receptor-mediated endocytosis is different from phaocytosis.

2)Distinguish between diffusion and active transport, in terms of
a)energy involvement
b)direction of molecular flow

3)chocolate mil has been a choice for many athletes, as it is a good source of protein, carbohydrates, and lipids. Suppose you were to coduct nutrient testing on a sample of chocolate milk. Describe
a) the tests you would perform and the reagents you would use
b)the results you would expect to find

Answer 1

1)Describe two ways that receptor-mediated endocytosis is different from phaocytosis.

receptor-mediated endocytosis is specific. it only allows special molecules to enter. there are receptors out the cell membrane. In Phagocytosis, the cell membranes goes toward the large molecule and forms a vesicle and engulfs it.

2)Distinguish between diffusion and active transport, in terms of
a)energy involvement
b)direction of molecular flow

Diffusion doesn't require energy; with/down the concentration gradient Active transport requires energy; against/up the concentration gradient
