Facilitated diffusion differs from simple diffusion because

What is the term for the type of passive transport in which a carrier molecule is required?

In protein synthesis,transcription is the transfer of genetic information from

Chromosomes are aligned in the center of the cell during

A phagocytic cell is likely to have increased numbers of

The genetic material of the cell is located in the

When a cell with an intracellular glucose concentration of 5 percent is placed in a 10 percent glucose solution,glucose molecules move from the 10 percent extracellular solution into the 5 percent intracellular solution by osmosis.

The cellular component that regulates the composition of the cytoplasm is the

Nuclear division that occurs in somatic cells is called

What is the term for the process of nuclear division in somatic,or body,cells?

The central region of the cell membrane is

In osmosis

A cell that normally has 46 chromosomes undergoes mitosis and cytokinesis to produce two cells,each with 23 chromosomes.

The movement of oxygen from a region of higher concentration to a region of lower concentration without the expenditure of energy is

DNA and RNA are both found inside the nucleus.

The outer and inner phosphate layers of the cell membrane are hydrophilic.

One of the functions of the proteins in the cell membrane is to

Lipids in the cell membrane act as receptor sites for hormone action.

A substance,such as glucose,that passes through the cell membrane by facilitated diffusion,requires a carrier molecule and energy from ATP.

What are the terms for the two main structural components of the cell membrane?
