Cellular Respiration quiz study guide

FADH2

NADH and ________ break down NAD to FAD2 2. electrons help to pump hydrogen through inner membrane of the mitochondria 3. hydrogens flow back through ATP synthase to make ATP 4. at the end of ETC oxygen picks up free hydrogens to form water.

Lactic acid

________ does: what makes our muscles burn during exercise.

Fermentation purpose

________: if cells do not have enough oxygen they will perform this process.

Anaerobics

________: glycolysis, lactic acid and alcoholic fermentation.

Glycolysis process

________: 1. glucose is broken down into two 3 carbon molecules using 2 molecules at ATP 2. the 3 carbon molecules are changed into pyruvate molecules and from 2 NADH and 4 ATP molecules.

Alcoholic location

________: happens by bacteria and small cells like yeast.

Krebs cycle process

________: 1. pyruvate molecule is broken down into another molecule and part is given off as carbon dioxide 2. the part that is not given off as carbon dioxide continues to break down into other molecules and releases NADH, FADH2 and ATP molecules.

Lactic acid

________ products: ________ and NAD+.

anaerobic

without air

aerobic

with air

cellular respiration

1. glycolysis 2. krebs cycle 3. electron transport chain (ETC)

glycolysis location

cytoplasm

glycolysis reactants

glucose and ATP

glycolysis process

1. glucose is broken down into two 3 carbon molecules using 2 molecules at ATP 2. the 3 carbon molecules are changed into pyruvate molecules and from 2 NADH and 4 ATP molecules

glycolysis main purpose

to make pyruvic acid for the krebs cycle

krebs cycle location

matrix of mitochondria (inside)

krebs cycle reactant

pyruvate molecules

krebs cycle process

1. pyruvate molecule is broken down into another molecule and part is given off as carbon dioxide 2. the part that is not given off as carbon dioxide continues to break down into other molecules and releases NADH, FADH2 and ATP molecules

kreb cycle main purpose

to take out pyruvate from glycolysis and make more energy carriers (ATP/NADH) and make carbon dioxide

ETC location

inner membrane of the mitochondria

ETC reactant

NADH and FADH2 and oxygen

ETC process

1

ETC purpose

to use energy carriers (NADH and FADH2) made earlier in the process to produce ATP energy

fermentation purpose

if cells do not have enough oxygen they will perform this process

lactic acid fermentation location

happens in our cells

lactic acid products

lactic acid and NAD+

lactic acid does

what makes our muscles burn during exercise

alcoholic location

happens by bacteria and small cells like yeast

alcoholic products

carbon dioxide, alcohol and NAD+

alcoholic does

what allows bread to rise (carbon dioxide is still given off)

anaerobics

glycolysis, lactic acid and alcoholic fermentation

aerobics

krebs cycle and electron transport chain
