Glycolysis
Where does glycolysis occur?
Cytoplasm
What stage of cellular respiration is repeated during fermentation?
Glycolysis
Where does Kreb/ Citric Acid cycle occur?
Mitochondria Matrix
Why are protons able to move from the intermembrane to the matrix space?
Facilitated diffusion (high to low)
Where do the high-energy electrons of glucose go throughout cellular respiration?
Electron carriers
What is being split during glycolysis, and what is it being split into?
Glucose (6C) is split into 2 pyruvate (3C)
What is being regenerated during fermentation?
NAD+
What enters the Kreb Cycle?
Acetyl-Coa
What are the products of oxidative phosphorylation?
Water and ATP
Which of the following molecules contains the most amount of energy:CH3OH , CH2O , CO2
CH3OH
List all the products of glycolysis
2 NADH + Net gain of 2 ATP+ 2 Pyruvate
Where does fermentation occur?
Cytoplasm of cells
List all the products of the kreb's cycle
6 NADH + 2 ATP+2 FADH2+ 4 CO2
What is happening as the electrons are moving through the chain of proteins?
What is being oxidized during cellular respiration, and what is it being oxidized into?
Glucose oxidized into carbon dioxide
What type of phosphorylation is occurring when we are making ATP during glycolysis?
Substrate-level phosphorylation
This type of fermentation produces an acidic product that gives fermented food a unique taste and benefits
Lactic Acid Fermentation
What happens to all the electron carriers being made in the Kreb Cycle?
Go to the electron transport chain
What energy is stored in the proton gradient and what energy is it converted to when it pass through the ATP synthase.
Protons have stored potential energy, and the stored potential energy is converted to mechanical energy as it passes through the ATP Synthase.
What is being reduced in cellular respiration, and what does it reduce to?
Oxygen is reduced into water
Where do we obtain the phosphate needed to produce 4 ATP?
Investment of 2 ATP and 2 inorganic phosphate.
Why is it that your muscle cells start doing fermentation under intense and long periods of exercise?
Oxygen is not being supplied fast enough to these cells, so to maintain doing the intense exercise, the cells will resort to doing fermentation, where 2 ATP can consistently be made.
In the Kreb Cycle, what do we start and end with?
Oxaloacetate
What enzyme makes ATP, and how can this enzyme make it?
Enzyme: ATP Synthase
How: Protons travel through it as they return to the matrix. In the process, it spins the motor of the protein, causing it to change shape, resulting in it then being able to grab ADP and P- to form ATP
Cell respiration is anabolic/catabolic, endergonic/exergonic, and anaerobic/aerobic process
Cell respiration is a catabolic, exergonic, and aerobic process.
