Q

light independent reaction

A

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

Q

omnivore

A

eats both plants and animals

17
Q

cellular respiration

A

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

18
Q

glycolysis

A

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

19
Q

Kreb’s cycle

A

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

20
Q

electron transport chain

A

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

21
Q

36 ATP

A

number of ATP produced from cellular respiration

22
Q

aerobic vs. anaerobic respiration

A

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

23
Q

lactic acid fermentation

A

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

24
Q

alcoholic fermentation

A

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