Q

A type of transport protein found in the plasma membrane of cells lining the inside of the intestine allows sodium ions to diffuse down their concentration gradient. The ions move through the transport protein, and into the cell. These transport proteins will use the kinetic energy of the diffusing sodium ions to bring glucose into the cells as well, against its concentration gradient. This process would best be described as

36
Q

Carbohydrates and proteins are built up from their basic building blocks by the:

A

removal of a water molecule between two units

46
Q

Choose which modification would line the uterine tubes and function as a “conveyer belt” to help move the fertilized egg towards the uterus.

A

cilia

47
Q

Cells spend most of their time in ____________ within the cell cycle.

48
Q

In the presence of water and the enzyme sucrase, sucrose can be broken down into its component monomers: fructose and glucose. What is this process?

A

hydrolysis

49
Q

Gases such as O2 and CO2 travelling through the plasma membrane down their concentration gradients is an example of __________.

A

simple diffusion

50
Q

Using the information below, how could this cell INCREASE its intracellular calcium (Ca) concentration?

Concentration of Calcium (Ca):

Inside the cell (intracellular environment) = 3% calcium

Outside the cell (extracellular environment) = 1% calcium

A

It could use active transport to transport extracellular Ca into the cell.

51
Q

The plasma membrane is made of phospholipids. What is responsible for its structure? Select all that apply.

A

The tails face toward the inside of the membrane because they are uncharged and hydrophobic and the heads face out (toward the water) because they are polar and hydrophilic.
