biology
What are the reactants of cellular respiration?
- C6H12O6 (sugar)
2. 6-O2 (oxygen)
What are the products of cellular respiration?
- 6 H20
2. Energy (in the form of ATP)
What phase of cellular respiration occurs in the cytoplasm of the cell?
Glycolysis
What are the 4 phases of Cellular Respiration?
- Glycolysis (Cytoplasm)
- Intermediate (Passage through the membranes
- Kreb’s Cycle (matrix of the mitochondria)
- ETC (the inner membrane of cristae)
Which of the 4 phases of of cellular respiration requires oxygen???
The Electron Transport Chain
BECAUSE: The O2 is the final electron acceptor
Which of the 4 phases of cellular respiration produces carbon dioxide?
The kreb’s cycle and the (link reaction)
which of the four phases of cellular respiration produce water?
oxidative phosphorylation…that happens in the Kreb’s Cycle
which of the 4 phases results in the production of ATP?
ETC
The Electron Transport Chain
How many ATP molecules total are produced for every molecule of Glucose that enters cellular respiration?
36/38
38 total are made, but 2 are used to get inside the inner membrane of the mitochondria.
What reactants must be present in the cell to produce ATP?
ADP
and a Phosphate
Other cellular processes when energy is necessary?
muscle movement
growth/metabolism
endo/exocytosis
active transport
What are the three high potential energy molecules for the cellular respiration phases?
ATP
NADH
FADHH
How many electrons in an H+ atom?
NONE
What is the reduced form for NAD???
NADH is reduced because it has the electrons gained during the process of reduction
Is glucose being reduced or oxidized?
Glucose is being oxidized, because it gives away its electrons to the NAD+ or the FADH+
