BIO 200

• 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

  Lactate fermentation
• fermentation that produces bread and winemaking

  Alcohol fermentation
