Metabolism and Cellular Respiration Quiz Flashcards
whats anabolism
when larger molecules are made from smaller ones
whats catabolism
breakdown of larger molecules into smaller ones
what does the sythnesis of ATP from ADP result from
energy captured as it is liberated from the catabolism of glucose
whats glycolysis
breakin gdown of glucose to form pyruvic acid
what does anaerobic mean
without oxygen
what does oxidation mean
loss of electrons and hydrogen ions
whats the objective of glycolysis
generate ATP
wehre does glycolysis occur
cytoplasm
whats the purpose of cellular respiration
to break down glucose and slowly release it as energy
what starts glycolysis and whats the final product
glucose; pyruvic acid
how many ATP are generated in glycolysis reaction? whats the net gain?
4 generated, net gain of 2
how many ATP are produced if glucose is completely broken down in the presence of oxygen
36
how many ATP are prdouced if glucose is broken down without oxygen
2
what does fermentation form
lactic acid or ethyl alcohol
what happens to the pyruvate prdouced in glycolysis if oxygen is avaliable
enters mitochondrie, gets oxidized, forms acetyl CoA which gets oxidized in the krebs cycle
what happens to pyruvate produced in glycolysis if oxygen is not availabe
stays in the cytoplasm and reduced to form lactic acid or ethyl alcohol
how many ATP does heach NAD 2H molecule make
3
how many ATP deoes each FAD 2H molecule produce
2
what is the net yeild of glycolysis
2 ATP, 2 NAD 2H
what is the net yeild of puryvate to acetyl CoA
2 NAd 2H
whats the net yeild of the krebs cycle
2 ATP, 6 NAD 2H, 2 FAD 2H
whats the total net yield in cellular respiration
4 ATP, 10 NAD 2H, 2 FAD 2H
where does electron transport occur
mitochondira
what does electron transport do
energy is released from the electrons which is used to phosphorylate ADP to ATP making oxygen the ultimate electron aceptor and causing the formation of water
