Question

A) In primary active transport ____ provides the energy required to "pump" the solute against it's concentration gradient. An example of this is the _________, which helps to move ___________ out of the cell.

B) Compounds can also cross the membrane by binding to specific receptors that lead to a process called _____________. An example of this seen when low density liporotein binds to its receptor on a cell. The process of __________ is a mechanism that allows compounds within a vesicle to be effictively transported across the plasma membrane and released into the extracellular fluid.

C) An amine atom can be bound to four R groups, but it then exists as a ________.

D) When acetylcholine binds to the nicitinic acetylcholine receptor the proein conformation changes and allows both ___________ and ___________ to pass through.

Explanation / Answer

B) Compounds can also cross the membrane by binding to specific receptors that lead to a process called __receptor-mediated endocytosis__. An example of this seen when low density liporotein binds to its receptor on a cell. The process of ___exocytosis____ is a mechanism that allows compounds within a vesicle to be effectively transported across the plasma membrane and released into the extracellular fluid.

C) An amine atom can be bound to four R groups, but it then exists as a ___ion (for example, NH4+ or ammonium ion).

D) When acetylcholine binds to the nicotinic acetylcholine receptor the protein conformation changes and allows both __Sodium ___ and _____potassium_ to pass through.
