cell respiration Flashcards
(24 cards)
what are the 3 main metabolic fates of glucose
1-starch
2-sucrose
3-cellulose
what does ATP stand for
adenosine triphosphate
what is the 2 main functions of ATP
1- transferable energy source within the cell
2- controllable release and storage of energy
what is oxidation
when an atom or molecule loses electrons
reduction
when an atom or molecule gains electrons
what is NAD+
important coenzyme for cellular respiration
what is NADP+
important coenzyme for photosynthesis
where does light dependent reaction of photosynthesis occur
in the thylakoid
what is the light dependent reaction of photosynthesis
the first phase of photosynthesis
what is the names of the photosynthesis pigments
photosystems I and II
what is photosystem I (p700) responsible for
- absorption of maximum near 700nm
- solar energy trapped by pigments
what is photosystem II (p680) responsible for
use solar energy to split water (photolysis)
what is the Calvin cycle
catalyzed reactions involved in the synthesis of a carbohydrate from carbon dioxide
where does the Calvin cycle occur
reactions occur in the chloroplast stroma
photosynthesis
process in which plants use chlorophyll to trap light energy and ten is used to synthesis carbohydrates
autotroph
an organism that can manufacture its own food
fermentation
process occurring when there is no oxygen available and energy is generated and an organic molecule (pyruvate) acts as a final electron acceptor
krebs cycle
process occurring under aerobic conditions in the mitochondria where energy is generated and oxygen acts as the final electron acceptor
oxidation phosphorylation
oxygen becomes the ultimate electron acceptor and water is formed in the the mitochondria `
metabolism
the sum of all chemical reactions in a cell
anabolism
process in which larger molecules are synthesized from smaller ones
catabolism
breakdown of larger molecules into smaller ones
glycolysis
breaking down of glucose to form pyruvate
where does glycolysis occur
cytoplasm
