1

photosynthesis

means "light- putting together"- is the process of converting light energy into food (glucose)

2

light reaction

first step in photosynthesis- water is split and 2 ATP formed

3

light independent reaction

also called the Dark or Calvin cycle it is the second step of photosynthesis- CO2 is joined to the hydrogen from the split water of the light reaction forming PGAL which can then be turned into glucose

4

thylakoid

where chlorophyll is found- site of the light reaction

5

stroma

where the light independent (dark) reaction takes place

6

chloroplast

the cell organelle where photosynthesis occurs

7

ATP

adenosine triphosphate- the energy molecule used by all cells

8

ADP

adenosine diphosphate- the molecule used by all cells to form ATP

9

phosphorylation

addition of a phosphate molecule to another molecule

10

de-phosphorylation

removal of a phosphate molecule from another molecule

11

heterotroph

"other- feeder" eats others for energy

12

photoautotroph

makes food using sunlight

13

chemoautotroph

makes food using chemicals and heat from the earth

14

herbivore

plant eater

15

carnivore

flesh eater

16

omnivore

eats both plants and animals

17

cellular respiration

process of using oxygen to convert the energy of glucose into the energy of ATP

18

glycolysis

takes place in the cytoplasm-means "glucose splitting" the first stage of respiration- no oxygen needed- results in 2 ATP formed

19

Kreb's cycle

takes place in the mitochondria-second stage of respiration- 6CO2 produced along with 2 ATP

20

electron transport chain

takes place in the mitochondria-third stage of respiration- 6 H20 produced along with 32 ATP

21

36 ATP

number of ATP produced from cellular respiration

22

aerobic vs. anaerobic respiration

aerobic means with air (oxygen) while anaerobic means without air (oxygen)

23

lactic acid fermentation

type of anaerobic respiration performed by animals when short on oxygen- forms 2 ATP along with lactic acid

24

alcoholic fermentation

type of anaerobic respiration performed by micro-organisms like yeast when short on oxygen- forms 2 ATP along with ethyl alcohol
