Cellular Respiration 1
What does Photosynthesis generate that is fuel for Cellular Respiration?
O2 (oxygen)
is a partial degradation of sugars that occurs without O2
fermentation
consumes organic molecules and O2 and yields ATP
aerobic respiration
What is the formula for Cellular Respiration?
C6H12O6 + 6 O2 --->6 CO2 + 6 H2O + energy
How many stages does harvesting energy from glucose have?
3
Where does NADH pass electrons?
electron transport chain
Does NAD+ accept or donate electrons?
accepts electrons
O2
the fuel (such as glucose)
What has to happen for the citric acid cycle to begin?
pyruvate must be converted to acetyl CoA
This stage of cellular respiration breaks down glucose into two molecules of pyruvate:
glycolysis
This stage of cellular respiration completes the breakdown of glucose:
citric acid cycle
This stage of cellular respiration has an electron transport chain and chemiosmosis. It also accounts for most of the ATP synthesis
oxidative phosphorylation
Where is the electron transport chain located?
inner membrane
Does the electron transport chain generate ATP directly?
no
What is the name of the protein enzyme that ha H+ moving back across the membrane?
ATP Synthase
What are the 2 processes of oxidative phosphorylation?
electron transport chain and chemiosmosis
How many ATP does oxidative phosphorylation make?
34 ATP
How many ATP, NADH, and FADH2 does the citric acid cycle produce per glucose molecule?
2 ATP, 6 NADH, and 2 FADH2
What is the net production of ATP, NADH, and Pyruvate in glycolysis?
2 ATP, 2 NADH, and 2 Pyruvate
explain anaerobic respiration
glycolysis takes place normal but the pyruvate is oxidised back to lactate with lactate dehydrogenase
explain the process of the electron transport chain
e are accepted from NADH and FADH, they pass along the ETC, everytime they pass from one to another energy is used to pump protons accross the membrane creating a difference in the gradient between the inner membrane space and the matrix
