IV CH 1

Question 1

Lipid

Answer 1

fats- combine hydrogen, carbon, and oxygen. doesn’t dissolve in water. stored as high energy

Question 2

hydrophobic

Answer 2

repelled by water

Question 2

hydrophilic

Answer 2

attracted to or soluble in water

Question 3

glucose

Answer 3

six-carbon (blood) sugar, used for energy in cells

Question 4

diabetes

Answer 4

high blood sugar levels not utilized properly. requires treatment to lower sugar levels

Question 5

glycogen

Answer 5

starch polysaccharide, used to store energy.

Question 6

proteins

Answer 6

make up 50% of dry weight in animals

Question 7

enzymes

Answer 7

protein molecules that speed up chemical reactions

Question 8

antibodies

Answer 8

infection fighting proteins. vets count amount in blood to determine what organism is causing sickness in their patients

Question 9

exocytosis

Answer 9

moving of the proteins to the outside of the cell membrane

Question 10

metabolism

Answer 10

all reactions going on in the cell

Question 11

anabolism

Answer 11

one of the two main types of metabolism: smaller molecules are combined into larger ones

Question 11

catabolism

Answer 11

one of the types of metabolism: large molecules broken into smaller molecules

Question 12

homeostasis

Answer 12

maintenance of ECF (liquid around living cells) & normal concentration of molecules

Question 13

diffusion

Answer 13

molecules move from higher to lower concentrations, continues until concentrations are equalized

Question 14

osmosis

Answer 14

water moves (outward) across the cell membrane to equalize the concentration. molecules dissolved can’t pass the membrane

Question 15

active transport

Answer 15

requires cell’s energy & enzymes for diffusion

Question 16

endocytosis

Answer 16

cell membrane wraps the particle and pinches off & moves into the cell in a vacuole

Question 16

benign

Answer 16

tumor localized to one area (well defined margin) & doesn’t spread throughout the body

Question 17

pathologist

Answer 17

interpret & diagnose changes in cells & tissues

Question 17

malignant

Answer 17

tumor more likely to invade surrounding tissue, cells break away & can move into bloodstream or lymph nodes

Question 18

metastasis

Answer 18

moving of a tumor from its original location
