INTRODUCTORY BIOLOGY OF CELLS
Where does glycolysis occur? - CORRECT-ANSWERS--cytoplasm
Where does pyruvate oxidation occur? - CORRECT-ANSWERS--
mitochondrial matrix
Where does the citric acid cycle occur? - CORRECT-ANSWERS--
mitochondrial matrix
,Where does the electron transport chain occur? - CORRECT-ANSWERS--
inner membrane of mitochondria
What goes into glycolysis? - CORRECT-ANSWERS--Glucose and 2 ATP
What comes out of glycolysis? - CORRECT-ANSWERS--2 pyruvate, 2 ATP, 2
NADH
How is glycolysis regulated? - CORRECT-ANSWERS--feedback inhibition
with PFK enzyme and ATP or citrate
What goes into pyruvate oxidation? - CORRECT-ANSWERS--2 pyruvate
What comes out of pyruvate oxidation? - CORRECT-ANSWERS--2 acetyl-
CoA, 2 NADH, 2 CO2
What goes into the citric acid cycle? - CORRECT-ANSWERS--2 Acetyl CoA
>>> (acetyl coenzyme A).
Acetyl-CoA is formed during the preparatory step, where the two-carbon
acetyl group is produced by the breakdown of carbohydrates, fats, or
proteins.
what comes out of the citric acid cycle? - CORRECT-ANSWERS--4 CO2, 6
NADH, 2 FADH2, 2 ATP
what does the acetyl attach to in the citric acid cycle? - CORRECT-
ANSWERS—oxaloacetate >>> oxaloacetate (OAA).
The enzyme responsible for this condensation reaction is citrate synthase.
This reaction forms a six-carbon molecule called citrate (citric acid), which
is why the cycle is named the citric acid cycle.
, citrate - CORRECT-ANSWERS--forms after acetyl attaches to oxaloacetate
what molecule is regenerated during citric acid cycle? - CORRECT-
ANSWERS--oxaloacetate
Regulation of the Citric Acid Cycle - CORRECT-ANSWERS--enzyme used in
pyruvate oxidation (PDH) is regulated and the citric acid cycle can only
run if it receives products from the enzymatic reaction
substrate-level phosphorylation - CORRECT-ANSWERS--The enzyme-
catalyzed formation of ATP by direct transfer of a phosphate group to ADP
from an intermediate substrate in catabolism.
- used in glycolysis and citric acid cycle
During cellular respiration, H+ are pumped from the _________________ into
the _________________. - CORRECT-ANSWERS--mitochondrial matrix, inter
membrane space
Water is created during cellular respiration when O2 takes receives
electrons and takes H+ from the ________________ - CORRECT-ANSWERS--
matrix
ATP synthase - CORRECT-ANSWERS---uses the proton gradient to produce
ATP through oxidative phosphorylation
primary metabolism - CORRECT-ANSWERS--essential for cell structure and
function
secondary metabolism - CORRECT-ANSWERS--synthesis of secondary
metabolites that are not necessary for cell structure and growth
