Answer 11

Polysaccharide, lipid, protein, and nucleic acid synthesis.

Question 12

Some catabolic reactions are required to degrade old and worn-out…?
Other catabolic reactions break down nutrients such as? (2)

Answer 12

Cellular components
Carbohydrates and lipids

Question 13

What can oxidation-reduction reactions do?

Answer 13

Basically, they can use the glucose from what we ate and turn it into fuel for our cells ATP.

Question 14

what can the basic process of the cell, transport of substances do?

Answer 14

They can transport compounds to another location of the cell and they can release the compounds out of the cell.

Question 15

How do cells communicate?

Answer 15

chemical and electrical signals

Question 16

Many cell types in the body can reproduce themselves through a process called

Answer 16

cell division

Question 17

what can cell division do?

Answer 17

cell division can replace old and damaged cells and they are used for growth and development.

Question 18

Cell reproduction is just

Answer 18

cell division

Question 19

Most animal cells have three basic components such as?

plasma membrane

Question 21

what are the 4 several functions of the plasma membrane.

Answer 21

structral support, communication with other cells, regulation of transport into and out of the cell, and cell identification.

Question 22

the main purpose of the plasma membrane is to phsically isolate the cell from its

intracellular space

Answer 26

the space within our cells that contains either the cytosol or intracellular fluid.

Question 27

extracellular space

Answer 27

the space outside our cells that contains extracellular fluid.

Question 28

what is the reason why the plasma membrane forms a barrier between the ECF and the cytosol? | it allows to control what? ## Footnote Synonyms: Cytosol= ICF
