• interstitial fluid.

• intercellular matrix.

• cytoplasm.

• cisternae.

Which is not considered part of the cytoplasm?

• Cytosol

• Nucleus

• Organelles

• Inclusions

Which is a non-membrane-bound organelle?

• Microtubule

• Lysosome

• Golgi apparatus

• Rough endoplasmic reticulum

• Mitochondrion

If the nutrient glycogen is found stored inside a cell, it is considered a(n)

• inclusion.

• membrane-bound organelle.

• non-membrane-bound organelle.

• pigment.

Which of the following choices describes three general functions cells must perform?

• Maintain shape, obtain nutrients, and dispose of wastes

• Respond to all hormones, maintain a waterproof barrier, give rise to gametes

• Grow until dividing, store complex carbohydrates, generate antibodies

The lipid that stabilizes the membrane at extreme temperatures and is found in the hydrophobic regions of the bilayer is

• the polar head.

• the nonpolar tails.

• cholesterol.

• glycolipid.

• glycocalyx.

The most abundant lipid of the membrane consists of a head and two tails. This type of lipid is

• a phospholipid.

• cholesterol.

• glycolipid.

• glycoprotein.

• a steroid.

Glycolipids are found on the

• outer layer of the cell membrane, and they help make the sticky sugar coating on its surface.

• middle layer of the cell membrane, and they function to transmit solutes through the membrane.

• inner layer of the cell membrane, and they provide scaffold support to the cell membrane.

• inside of the cell, where they are a source of high-energy nutrition to power mitochondria.

Which type of protein is used by cells of the immune system to distinguish normal cells from foreign or infected cells?

• Anchoring proteins

• Ligands

• Cell adhesion proteins

• Identity markers

• Transport proteins

Movement of a substance from an area of higher concentration to one where it is less concentrated is known as

• equilibrium.

• active transport.

• diffusion.

• facilitation.

• selective transport.
