Question 1

Active transport-

Answer 1

energy-requiring process in which transport proteins bind with particles and move them through a cell membrane

Question 2

Diffusion

Answer 2

A type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them.

Question 3

Endocytosis

Answer 3

process by which a cell takes in a substance by surrounding it with the cell membrane.

Question 4

Enzyme

Answer 4

A type of protein that regulates nearly all chemical reactions in cells

Question 5

Exocytosis-

Answer 5

a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.

Question 6

Metabolism-

Answer 6

he total of all chemical reactions in an organism

Question 7

Mixture

Answer 7

a combination of substances in which the individuals substances do not change or combine chemically but instead retain their own individual properties; can be gases,solids,liquids, or any combination

Question 8

Passive transport-

Answer 8

movement of substances through a cell membrane without the use of cellular energy; includes,diffusion,osmosis, and facilitated diffusion.

Question 9

Photosynthesis

Answer 9

The process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water and give off oxygen

Question 10

Fermentation-

Answer 10

a process by which oxygen-lacking cells and some one-celled organisms release small amounts of energy from glucose molecules and produce wastes such as alcohol carbon dioxide,and lactic acid.

Question 11

Inorganic compound-

Answer 11

compound, such as H2O, that is made from elements other than carbon and whose atoms usually can be arranged in only one structure.

Question 12

Organic compound

Answer 12

compounds that always contain hydrogen and carbon; carbohydrates.lipids,proteins, and nucleic acids are organic compounds found in living things.

Question 13

Osmosis-

Answer 13

a type of passive transport that occurs when water diffuses through a cell membrane.

Question 14

Cellular respiration-

Answer 14

Chemical reactions occur that break down food molecules into simpler substances and release their stored energy
