What are the four main stages of aerobic resperation
Glycolysis, link reaction, krebs cycle, electron transport chain
glycolosys means what
the breaking down of glucose
what is the purpose of NADH
electron to electron transport chain
how many times does the krebs cycle repeat
2x the number of glucose molecules
what happens to CO2 created in these cycles
it is breathed out
how does hydrogen ions flow
high to low concentration
how many ATP molecules are produced per glucose mulecule by the ETC
32 ATP
why do cells carry out cellular resperation
to break down food to make energy
how does the body get glucse
from eatingw
how does the body get oxygen
from breathing
how does the body get ADP
Breaking down ATP
A folded mitochondria will make more ATP because why
there is more surface area to use
What Cellular resperation process stops in the absence of O2
ETC and the krebs cycle
fermentation types
Alcoholic and lactic acid
Alcoholic fermentation
procuces ethonol and CO2, dead end process, cannot reverse
Lactic acid fermentation
produces lactic acid, reversable
both
start with pyruvate, convert NADH back t NAD+, does not generate ATP
