1

Glycolysis

anaerobic process in which glucose is split into two molecules of pyruvic acid

2

fermentation

anaerobic process in which either lactic acid or alcohol is produced

3

Krebs cycle

process in aerobic respiration that takes place in the matrix of the mitochondria; 2 ATP, NADH, FADH2, and CO2 are produced; AKA citric acid cycle

4

chlorophyll

green pigment that captures the suns energy

5

stroma

fluid portion of the chlorplast

6

light dependent reactions

AKA light reactions; reactions in photosynthesis that split a molecule of water into H+ and oxygen; takes place on the thylakoid membrane

7

light independent reactions

AKA dark reactions and Calvin cycle; reactions in photosynthesis in which carbon dioxide enters and makes glucose; takes place in the stroma

8

ATP synthase

enzyme used in making ATP

9

electron transport chain

process in aerobic respiration that hydrogen ions give up their electrons to help build ATP; takes place on the cristae of the mitochondria; produces 32 ATP

10

photosystem

light collecting unit of the chloroplast

11

thylakoid membrane

part of the chloroplast where the light reactions take place

12

active transport

transport of materials across a membrane from low to high; requires energy (ATP); examples - endocytosis and exocytosis

13

passive transport

transport of material across a membrane from high to low; does not require energy; examples- diffusion, osmosis, and facilitated diffusion

14

lipid bilayer

main component of the plasma (cell) membrane

15

cytoplasmic streaming

movement of the cytoplasm within a cell

16

endocytosis

type of active transport; moving materials into the cell from low to high; examples- pinocytosis and phagocytosis

17

exocytosis

type of active transport; moving materials out of the cell from low to high; examples - hormones or waste leaving the cell

18

phagocytosis

type of endocytosis; moving food/large particles into the cell from low concentration to high concentration

19

pinocytosis

type of endocytosis; moving water/liquid into the cell from low to high concentration

20

isotonic solution

dynamic equilibrium is established immediately; the concentration of solutes is equal on both sides of the cell; the cell stays the same; good for animal cells

21

hypertonic solution

concentration of solutes is higher on the outside than on the inside of the cell; the cell will shrink; causes plasmolysis in plant cells- bad for both plant/animal cells

22

hypotonic solution

concentration of solutes is lower on the outside than on the inside of the cell; the cell will swell - animals cells lyse/plant cells create turgor pressure - good for plant cells bad for animal cells
