Answers 100% Pass
What are the 3 phases of the cellular respiration process? - ANSWER✔✔-
glycolysis, the citric acid cycle, and the electron transport chain
Where in the cell does the glycolysis part of cellular respiration occur? -
ANSWER✔✔-the cytosol
What is the glycolysis part of cellular respiration's purpose? -
ANSWER✔✔-A molecule of glucose is split to release energy
Where in the cell does the Krebs (Citric Acid) cycle part of cellular
respiration occur? - ANSWER✔✔-the mitochondrial matrix
What is the Krebs' cycle purpose? - ANSWER✔✔-generates a pool of
chemical energy, generating 1 ATP, 3 NADH and 1 FADH2

, What is the electron transport's purpose in the cellular respiration? -
ANSWER✔✔-produces 32 ATP
How many ATP are made in the glycolysis part of cellular respiration? -
ANSWER✔✔-4
How many ATP are made in the Kreb's cycle part of cellular respiration? -
ANSWER✔✔-1
How many ATP are made in the electron transport part of cellular
respiration? - ANSWER✔✔-none
In which phase of cellular respiration is carbon dioxide made? -
ANSWER✔✔-Kreb's cycle (citric acid cycle)
What are NAD+ and FAD? - ANSWER✔✔-function as electron carriers
What do NAD+ and FAD do and what do they become? - ANSWER✔✔-
Carry and donate the electrons to the Electron Transport chain, they
become NAD+ and FAD again and return to the Kreb's cycle.
