Question

match the following descriptions to the appropriate protein molecule.
channels

1. anchor cell to extracellular matrix

membrane - bound enzymes

1. allow selective transport of ions or molecules

integrins

1. use atp to transport solutes

signal transduction receptors

1. transmit information into cell

protein pumps

1. catalyze reactions which take place within or along the membrane surface

question 19 (1 point)

Explanation:

Channels are membrane - spanning proteins that allow selective transport of ions or molecules. Membrane - bound enzymes catalyze reactions within or along the membrane surface. Integrins anchor the cell to the extracellular matrix. Signal transduction receptors transmit information into the cell. Protein pumps use ATP to transport solutes.

Answer:

1. Integrins
2. Channels
3. Protein pumps
4. Signal transduction receptors
5. Membrane - bound enzymes
