What kind of process does cellular respiration show?
Catabolic (process of breaking complex molecules into smaller molecules) Anabolic (building complex molecules using smaller molecules)
part of the cell that serves as the site of ATP production and Krebs cycle
Mitochondrial matrix
responsible for holding the protons that are pumped out of the matrix
Intermembrane space
molecules that are produced during and after cellular respiration
Water, Carbon dioxide, and ATP
Which is involved in the process of oxidation
Loss of Hydrogen atom
Which of the following is involved in the process of reduction?
Gain of Hydrogen atom
this explains why people with diabetes have high levels of sugar in the blood
Glucose cannot be absorbed by the cells for respiration
this happens to Red Blood Cells (RBCs) when glycolysis is disrupted
RBCs cannot function well and may lead to their death as they do not have mitochondria.
part of the structure of ATP is broken to release energy
Phosphoanhydride bonds
products of cellular respiration
CO2, ATP, H20
Where in mitochondria does the Krebs cycle take place
Matrix
this happens to the oxygen molecule when it accepts electrons
It splits into two.
this is true about fermentation
it happens in the muscle cells of humans
electron carriers in cellular respiration
NAD and FAD
In Eliza's culinary class, they are asked to make unleavened bread as part of their performance task. Unleavened bread does not contain a rising agent like yeast. Why do you think yeasts are not used to prepare such bread?
Yeast undergoes fermentation and releases CO2 during the process.
this molecule enters the energy-harvesting phase of glycolysis
Glyceraldehyde-3-phosphate
this is a product of phosphorylation
Glucose-6-phosphate
If there are four molecules of glucose that undergo glycolysis, how many ATP molecules are produced in the energy-harvesting phase?
16 (because there are 4 ATP molecules produced after energy harvesting stage so 4x4= 16 ATP molecules)
these are the enzymes used during glycolysis
Hexokinase
Aldolase
Triosephosphate kinase
In this process, NAD+ is used in glycolysis
Formation of 1,3-bisphosphoglycerate
this is produced at the end of glycolysis
pyruvate
For every glucose molecule, how many molecules of ATP are used during the energy-investment phase of glycolysis
2
Which of the following reactions are correctly paired?
phosphorylation of fructose-6-phosphate and the formation of fructose-1,6-bisphosphate
this molecule enters the Krebs cycle
Acetyl-CoA
this process produces GTP
When succinyl-CoA releases the coenzyme A
If there are three molecules of ATP produced from the oxidation of one NADH molecule, what is the total number of ATP molecules produced from NADH molecules that came from the Krebs cycle and transition reaction?
24
this enzyme catalyzes the isomerization of citrate to isocitrate
Aconitase
malate needs to be oxidized
to form and regenerate oxaloacetate
Aside from NADH, electron carrier involved in the Krebs cycle
FADH2
glucose-6-phosphate is isomerized to its isomer fructose-6-phosphate in glycolysis
Which of the following reactions or processes produces ATP?
When hydrogen ions pass through the ATP synthase
this cytochrome passes the electrons to cytochrome c
Cytochrome c1
this process causes the pumping of hydrogen ions into the intermembrane space
the electron transport through multiprotein complexes
What might happen if hydrogen ions can easily diffuse through the inner membrane without the aid of carrier proteins
ATP molecules will be produced from chemiosmosis.
this process results in the formation of water molecules
formation of ubiquinol when ubiquinone receives electrons
enzyme not used in fermentation
Thiamine pyrophosphate
in anaerobic respiration, this causes the formation of acetaldehyde
Decarboxylation of pyruvate
process in anaerobic respiration, which produces ATP
Glycolysis
fermentation that produces yogurt and cheese-making
