Photosynthesis and Respiration

Question 1

photosynthesis

Answer 1

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

Question 2

light reaction

Answer 2

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

Question 3

light independent reaction

Answer 3

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

Question 4

thylakoid

Answer 4

where chlorophyll is found- site of the light reaction

Question 5

stroma

Answer 5

where the light independent (dark) reaction takes place

Question 6

chloroplast

Answer 6

the cell organelle where photosynthesis occurs

Question 7

ATP

Answer 7

adenosine triphosphate- the energy molecule used by all cells

Question 8

ADP

Answer 8

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

Question 9

phosphorylation

Answer 9

addition of a phosphate molecule to another molecule

Question 10

de-phosphorylation

Answer 10

removal of a phosphate molecule from another molecule

Question 11

heterotroph

Answer 11

“other- feeder” eats others for energy

Question 12

photoautotroph

Answer 12

makes food using sunlight

Question 13

chemoautotroph

Answer 13

makes food using chemicals and heat from the earth

Question 14

herbivore

Answer 14

plant eater

Question 15

carnivore

Answer 15

flesh eater

Question 16

omnivore

Answer 16

eats both plants and animals

Question 17

cellular respiration

Answer 17

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

Question 18

glycolysis

Answer 18

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

Question 19

Kreb’s cycle

Answer 19

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

Question 20

electron transport chain

Answer 20

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

Question 21

36 ATP

Answer 21

number of ATP produced from cellular respiration

Question 22

aerobic vs. anaerobic respiration

Answer 22

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

Question 23

lactic acid fermentation

Answer 23

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

Question 24

alcoholic fermentation

Answer 24

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