function andsurvival of the cell.

A) is the site of protein synthesis gg gg gg gg gg
B) contains the genetic code gg gg gg
C) transforms cellular energy gg gg
D) initiates aerobic metabolism gg gg
2 Although energy is not made in mitochondria, they are
gg gg gg gg gg gg gg gg
knownas the power plants of the cell because they:
gg gg gg gg gg gg gg gg nn
A) contain RNAfor protein synthesis. gg g gg gg
B) utilize glycolysis for oxidative energy.

C) extract energy from organic compounds.
gg gg gg gg
D) store calcium bonds for muscle contractions.

membrane isformed by a lipid bilayer, most of the
gg gg gg gg gg gg gg gg gg
specific membrane functions are carried out by:

A) bound and transmembrane proteins. gg gg gg
B) complex, long carbohydrate chains. gg gg gg

that:

B) accumulate within cell gap junctions. gg gg gg gg
C) bind to contractile microfilaments.

gg gg gg gg gg
metabolism,provides energy by:
gg gg gg
A) removing the phosphate bonds fromATP. gg gg gg gg g
B) combining hydrogen and oxygen to gg gg gg gg
formwater.

thecells and the number of layers. Which of the following

is a correctly matched description and type of epithelial

tissue?

all cells rest on basement membrane

gg gg gg gg gg gg
for:
gg
A) providing a fibrous framework for capillaries. gg gg gg gg gg
B) synthesis of collagen, elastin, and gg gg gg nn
reticularfibers.

C) forming tendons and the fascia that gg gg gg gg gg
covers muscles. n

10 Although all muscle tissue cells have some similarities,
gg gg gg gg gg gg gg
smooth muscle (also known as involuntary muscle)
gg gg gg nn gg gg gg
differs by:

A) having dense bodies attached to gg gg gg gg
actinfilaments. gg

Mbands.
