Question
Use the carbon cycle at the right to answer questions 52-53. Where does the endoskeleton on the front desk fit in the carbon cycle? Which step in the carbon cycle occurs in anaerobic respiration? Use the choices at the right to answers question 54-57. Choices may be used once, more than once, or not at all. Glycolysis occurs here. a) cytoplasm b) mitochondrial inner membrane c) mitochondrial inner membrane c) mitochondrial matrix d) plasma membrane e) thylakoids The Krebs cycle occurs here in eukaryotic cells. The Krebs cycle occurs here in prokaryotic cells. Oxidative phosphorylation occurs here in prokaryotes. The enzyme cyclooxygenase (COX-2) converts arachidinonic acid (figure below) to the chemical messenger for pain, prostaglandin. Aspirin (figure below) is a widely used nonsteroidal anti-inflammatory drug (NSAID). Aspirin was discovered in willow plants. How does aspirin work? a) noncompetitive inhibitor b) enzyme poison c) blocks the electron transport system d) competitive inhibitor A young animal has never had much energy. He is brought to a veterinarian for help and is sent to the animal hospital for some tests. There they discover his mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal of the following, which is the best explanation of his condition? a) His cells cannot move NADH from glycolysis into the mitochondria. b) His cells contain something that inhibits oxygen use in his mitochondria. c) His cells have a defective electron transport chain, so glucose goes to lactate instead of to acetyl CoA. d) His cells lack the enzyme in glycolysis that forms pyruvate. e) His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane. A 23-year-old women with weakness for three months demonstrated a deficiency of flavoprotein-ubiquinone oxidoreductase. Riboflavin, improved muscle strength. This enzyme is part of a) glycolysis. b) lactic acidosis. c) the electron transport chain. d) the pentose phosphate shunt. Patients with Leigh Disease lack pyruvate decarboxylase. These patients will most likely have a) a higher body temperature. b) lactic acidosis. c) an over-active Krebs cycle. d) alcohol intoxication. E) more efficient glycolysis.Explanation / Answer
Use the choices at right to answer questions 54 - 57. Choices may be used once, more than once, or not at all.
54. Glycolysis occurs here :
a) Cytoplasm
Glycolysis means break down glucose. It takes place it two steps, the first step occurs in cytoplasm which is the thick fluid present in living cells and it yeilds small amount of energy and two molecules of pyruvate and the other step occurs in mitochondria.
55) The krebs cycle occurs here in eukaryotic cells:
c) mitochondrial matrix
Krebs cycle is a part of cellular respiration which is used by all aerobic organism to generate energy. Mitochondrial matrix is a viscous fluid present in the inner membrane of the mitochondria where cellular respiration takes place.
56) The Krebs cycle occurs here in prokaryotic cells:
a) cytoplasm
Krebs cycle is a part of cellular respiration which is used by all aerobic organism to generate energy. In prokaryotic cells it take place in cytoplasm which is the thick fluid present in living cells.
57) Oxidative phosphorylation occurs here in prokaryotes.
d) plasma membrane
Oxidative phosphorylation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing energy which is used to reform ATP. Oxidative phosphorylation for prokaryotes occurs in plasma membrane which is the membrane that separates the interior of all cells from the outside environment.
