Cellular Respiration Flashcards
Source of energy for cellular respiration
ATP (adenosine triphosphate)
what type of macromolecule is ATP
and composition
nucleic acid
- pentose sugar (ribose)
- base (adenine)
- 3 phosphates
process of why ATP is able to release energy
hydrolyzation
what happens in HYDROLYZATION OF ATP
3rd phosphate is cut off (releases energy) in order to become more stable (turn into ADP)
AEROBIC Cellular Respiration Equation
C6 H12 O6 + 6O2 -> 6CO2 + 6H20 + ATP
Cellular respiration vs photosynthesis
products and reactants are inverted
P: makes glucose (6CO2 + 6H2O -> C6 H12 O6 + 6O2
C: make ATP from glucose (C6 H12 O6 + 6O2 -> 6CO2 + 6H20 + ATP)
1st step of Cellular Respiration
Glycolysis
Where does glycolysis occur and does it require O2 or not?
- cytoplasm
- anaerobic
What happens in glycolysis?
- reactants and end products
glucose -> 2 pyruvate, 2 ATP molecules, & 2 NADH
Chemical composition of pyruvate
C3
what is NADH
coenzyme that helps in electron transfer which is helpful in making more ATP
After production in glycolysis, what molecules are transferred, where, how, and what happens?
2 pyruvate transferred to mitochondria via ACTIVE TRANSPORT
2 pyruvate -> (oxidation) -> 2 acetyl CoA + CO2 + 2 NADH
2nd step of Cellular Respiration
Krebs Cycle (Citric Acid Cycle)
Where does krebs cycle occur and does it require O2 or not?
mitochrondial matrix
requires aerobic
What happens in krebs cycle?
- reactants and end products
2 acetyl CoA -> CO2 + 2 ATP + 6 NADH + 2 FADH2
