plants part 3 Flashcards
Where does most of the mass of a
tree come from?
the air
In aerobic respiration, which reactant is
oxidized and which is reduced?
glucose becomes
oxidized, oxygen becomes reduced,
ox·i·da·tion
it means the substance that gives away electrons
Aerobic Respiration
A is a ______ process
catabolic
(glucose) broken down to give
carbon dioxide
and water
Redox reactions respiration is
transfer electrons from ______ to ______
from glucose (oxidized) – to oxygen (reduced)
4 Stages of
Aerobic Respiration
Glycolysis 2. Formation of acetyl CoA 3. Citric acid cycle 4. Electron transport chain and chemiosmosis
Formation of Acetyl CoA
1 pyruvate molecule
Acetyl group + coenzyme A
1 NADH produced per pyruvate
1 pyruvate molecule loses 1 molecule of
– loses 1 molecule of carbon dioxide
Acetyl group + coenzyme A
produce acetyl CoA
how many NADH produced per pyruvate
1
the citric acid cycle contains what compounds
4-carbon and 5- carbon
Electron Transport Chain
Electrons transfer
from one electron acceptor to another in mitochondrial inner membrane
Electrons reduce molecular _____
– forming ____
oxygen, water
Glycolysis occurs in the _____ while All other stages in the
cytosol mitochondria
