Concept explainers
(a)
Interpretation: The enzyme denoted by the acronym LDH has to be predicted.
Concept introduction: The concentration of enzymes is useful for obtaining information about a heart attack. The blood levels of the three enzymes commonly assayed in heart attack situation are: creatine phosphokinase (CPK), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH).
(b)
Interpretation: The enzyme denoted by the acronym AST has to be predicted.

- Define the following terms: a. enterocyte b. N-glycan c. O-glycan d. glycogen e. glycosaminoglycanarrow_forwardDefine the following terms: a. lactone b. aldaric acid c. aldonic acid d. uronic acid e. epimerizationarrow_forwardWhich of the following statements regarding glucose is NOT true? a.)Glucose is a monosaccharide sugar b.)Glucose can be metabolized by both aerobic and anaerobic metabolism c.)The normal blood glucose concentration is 4-7 mmol/l d.)A high blood glucose concentration is called hypoglycemiaarrow_forward
- The catalytic activity of enzymes depends on the presence of appropriate environmental conditions. Pepsin is a digestive enzyme found in the stomach and facilitates the digestion of large proteins. If pepsin is removed from this acidic environment of the stomach and is instead placed in a more basic environment, it will cease to function. Describe the specific effect that a change in environmental pH will have on pepsin and explain how this change can lead to inhibition of its catalytic activity. Respond in 4 to 6 complete sentences.arrow_forwardWhich enzyme is necessary for the "degredation of peptone."arrow_forwardThe following statements are either True or False. Please label accordingly. a. L-Amino reductase is an enzyme. b. Allosteric enzymes are composed of two or more protein chains. Heavy metals are examples of inhibitors. They function by binding to sulfur on cysteine amino acid residues. C. d. A reversible noncompetitive inhibitor temporarily blocks an enzyme's active site. Enzymes don't denature as easily as smaller proteins when heated or stressed due to their complex secondary and tertiary structure. e. Oxidative phosphorylation is the biochemical process by which ATP is synthesized from ADP when protons cross the inner mitochondrial membrane. f. g. DNA and RNA strands differ only in the fact that DNA forms a double helix. h. There is no secondary structure in RNA strands.arrow_forward
- The following enzymes belong to the same class of enzymes, except for A. Chymotrypsin B. Thrombin C. Lysozyme D. Alcohol dehydrogenase E. Elastasearrow_forwardAn enzyme with high activity in an acidic environment would be _____________________ pepsin amylase gatrin sucrase trypsinarrow_forwardLesch nyhan syndrome is due to deficiency of which enzyme ?arrow_forward
- For each of the following examples, indicate whether the drug is acting on physical process, chemical process or enzymatic system (your answer should be only; Physical, Chemical or Enzymatic). A. A drug is used as an antidote in lead poisoning and acts by binding to lead particles in body (chelation therapy). B. A drug acts to reduce flatulence and acts by reducing the surface tension of intestinal gas bubbles in the GI tract (e.g. Simethicone). C. A drug competes with alpha-glucosidase in intestine to reduce glucose conversion from disaccharides (e.g. Acarbose).arrow_forwardWhat are the chemical reactions in the body that are not involved cellular metabolism? Kindly discuss how these chemical reaction work.arrow_forwardDefine the following terms:a. cytochromeb. glycerol phosphate shuttlec. malate-aspartate shuttled. uncoupling proteine. oligomycinarrow_forward
