Cellular Respiration
Where do organisms get their energy from?
Food
The process of glycolysis takes place on what cellular respiration pathway?
Anaerobic
Where does the kreb cycle happen?
Matrix (innermost part of the mitochondria)
How many ATP are produced during the electron transport chain?
32 ATP
Fermentation happens in the absence of _________.
Oxygen
Is the process of energy conversion that releases energy from food in the presence of oxygen.
Cellular Respiration
One molecule of glucose is broken down into 2 molecules of _____________.
Pyruvic acid
During the kreb cycle pyruvic acid is broken down into ____________.
Carbon Dioxide
How are high-energy electrons passed to the electron transport train?
From NADH and FADH2
Where does fermentation take place?
Cytoplasm
What is the difference between calorie and Calorie?
calorie- the amount of energy needed t0o raise the temperature of 1 gram of water 1 degree Celsius
Calorie- is used on food labels and is a kilocalorie
For the process of glycolysis to start, what has to be present?
2 ATP molecules
Pyruvic acid is converted into acetic acid to allow the bonding to what compound?
coenzyme A
The electron transport chain uses the high-energy electrons from the kreb cycle to
Move H+ ions across the inner mitochondrial membrane
What type of reaction occurs for the conversion of pyruvic acid into lactic acid?
Chemical
Why is there a global balance between photosynthesis and cellular respiration?
Photosynthesis removes carbon dioxide from the atmosphere and produces oxygen while cellular respiration uses oxygen for energy and creates carbon dioxide.
Four high-energy electrons are passed to
electron carrier, NAD+
How is citric acid created in the kreb cycle?
Acetyl- CoA combines with a 4-carbon compound
At the end of the electron transport chain an enzyme combines the electrons with the hydrogen ions, and oxygen for the production of __________.
Water
What is the equation of alcoholic fermentation?
Pyruvic acid + NADH ---> Alcohol + Carbon Dioxide + NAD+
What is the chemical equation of cellular respiration?
oxygen + glucose --> carbon dioxide + water + energy
How many overall molecules of ATP are produced in the process of glycolysis?
4 ATP
one molecule of glucose results in how many turn of the kerb cylce?
2 complete turns
What role does oxygen play in the electron transport chain?
Oxygen is the final electron receptor meaning that low-energy electrons could not exit
How does fermentation allow for glycolysis to continue?
Allows for NADH to be converted back to NAD+ by passing high-energy electrons to pyruvic acid
