Cellular Physiology

Question 1

Glycocalyx

Answer 1

combinations of carbohydrates and lipids (glycolipids) and proteins (glycoproteins) on outer surface; how cell senses

Question 2

Glycolipids

Answer 2

Membrane carbohydrates that are covalently bonded to lipids.

Question 3

Glycoproteins

Answer 3

Membrane carbohydrates that are covalently bonded to proteins.

Question 4

What are the 3 mediated transport mechanisms?

Answer 4

Facilitated diffusion

Active Transport

Secondary Active Transport

Question 5

facilitated diffusion

Answer 5

Movement of specific molecules across cell membranes through protein channels

Question 6

active transport

Answer 6

the movement of materials through a cell membrane using energy (ATP)

Question 7

secondary active transport

Answer 7

Form of active transport which does not use ATP as an energy source; rather, transport is coupled to ion diffusion down a concentration gradient established by primary active transport.; symport and antiport

Question 8

symport

Answer 8

A membrane transport process that carries two substances in the same direction across the membrane.
