cellular respiration Flashcards
what is cellular respiration?
the process of generating energy (ATP) in cells by using the chemical energy stored in glucose.
what makes up ADP + Pi
adenosine, phosphate, Pi
what is ADP + Pi
a low energy compound ready for regeneration by chemical energy.
what is ATP
high energy
respiration is a …. pathway
catabolic
Respiration is used to transfer the chemical energy to …. reactions where energy is required.
anabolic
what’s the aerobic respiration equation?
oxygen + glucose + ATP + water + carbon dioxide
what are the 3 stages of respiration?
1) Glycolysis
2) Citric acid cycle
3) Electron transport chain
where does glycolysis occur?
the cytoplasm
what’s the substrate in Glycolysis?
glucose
what are the products of glycolysis?
- pyruvate
- hydrogen
- ATP
is glycolysis aerobic or anaerobic
anaerobic
why is ATP required during the energy investment phase of glycolysis?
required for the phosphorylation of glucose and intermediates leading to a bigger ATP payoff.
what is phosphorylation?
requires ATP and involves the transfer of the final phosphate to molecule in order to activate them and make them more likely to react.
what is the net gain of ATP during Glycolysis?
2
fate of products in glycolysis?
NAD —> to electron transport chain
ATP —> cell activities
pyruvate —> to citric acid cycle
where does the citric acid cycle occur
matrix of mitochondria
does the citric acid cycle need oxygen? how many ATP is made
yes oxygen is required, 2 ATP is made
what’s involved in the citric acid cycle (name in order)
pyruvate
acetyl group
acetyl coenzyme A —— coenzyme A
oxaloacetate —— citrate
where does the electron transport chain occur?
the inner mitochondrial membrane
does the electron transport chain require oxygen? how many ATP is made?
yes it requires oxygen, 2 ATP is made
