AP CH 3 & 4

Main cell structures include all of the following except:

• Organelles

• Plasma Membrane

• Blood P

• Cytoplasm

The major energy production site of the cell is the:

• Golgi Appa

• Mitochondrin

• Endoplasmic Reticulum

• Ribosome

Which of the following is a functional characteristic of ribosomes?

• Manufacture of mRNA

• Protein Synthesis

• DNA

• Housing DNA

The presence of this substance in the cell membrane prevents it from breaking easily.

• cholesterol

• protein

• phospholipids

• glycoprotein molecules

All of the following are examples of passive transport except:

• filtration

• osmosis

• endocytosis

• dialysis

A solution that contains a higher concentration of salt than a living red blood cell would be:

• isotonic

• hypotonic

• hypertonic

• homeostatic

Flagella are examples of:

• cell fibers

• chrososomes

• centrioles

• cell extensions

The cytoskeleton does all of the following except:

• support the endoplasmic reticulum, mitochondria, and "free" ribosomes

• form projections that extend the plasma membrane

• form the fluid framework for the plasma membrane

• help to increase the surface area to allow for greater absorption

An example of "carrier-mediated passive transport" is the:

• movement of carbon dioxide out of all cells

• movement of sodium ions into nerve cells as they conduct an impulse

• trapping of large protein molecules by some body cells

• diffusion of glucose molecules into most cells

A decrease in cell size is called:

• atrophy

• lyse

• osmosis

• plasma membrane
