QUESTION 20 As a group, all the chemical reactions that constantly occur within the body are called: anabolism catabolism metabolism homeostasis QUESTION 21 The reaction of glucose fructose sucrose is an example of catabolism electrolysis anode discharge anabolism

QUESTION 24 Which is true about metabolism? Pick all that apply. It consists of anabolism and catabolism. In catabolism, complex metabolites are broken down and this process commonly involves oxidation of the metabolites. In anabolism, the energy released from the process is conserved in ATP. NADPH often serves as an electron donor to reduce metabolites. NADH is often a product of catabolism. A metabolic pathway consists of only one reaction. The flow of metabolites through a pathway is regulated by enzymes that definitely follow Michaelis-Menten (M-M) model.

1) The sum of all biosynthetic reactions in a cell is known as: A) metabolism. B) anabolism. C) synthantabolism. D) catabolism. 2) Based on the functional roles of phosphate in various microbial metabolisms, deduce which compounds phosphate exists as in microorganisms. A) neither organic nor inorganic compounds B) both organic and inorganic compounds C) organic compounds D) inorganic compounds 3) Which is an example of a micronutrient? A) arginine B) iron C) inorganic phosphorous D) vitamin B12 4) To ensure growth of a newly discovered bacterium with unknown nutritional requirements, it would be best to begin with a ________ medium rather than a ________ medium. A) complex / minimal B) selective / complex C) selective / differential D) minimal / complex 5) The portion of an enzyme to which substrates bind is referred to as the: A) active site. B) junction of van der Waals forces. C) substrate complex D) catalytic site. 6) What is the difference between a coenzyme and a prosthetic group? A) Coenzymes are organic cofactors and prosthetic groups are inorganic cofactors. B) Coenzymes are essential for an enzyme's function and prosthetic groups only enhance its reaction rate. C) Coenzymes require additional ions to bind to enzymes but prosthetic groups are able to directly interact with enzymes. D) Coenzymes are weakly bound whereas prosthetic groups are strongly bound to their respective enzymes. 7) If an oxidation reaction occurs: A) a cell is undergoing aerobic respiration, because oxygen is being used. B) simultaneous reduction of a different compound will also occur, because electrons do not generally exist alone in solution. C) a reduction reaction would not occur, because they are opposite reaction mechanisms. D) another oxidation reaction will occur for a complete reaction, because one oxidation event is considered a half reaction. 8) The Embden-Meyerhof-Parnas pathway is another name for: A) glycolysis. B) the citric acid cycle C) electron transport. D) NADH production. 9) Which of the following is a common long term energy storage polymer in microorganisms? A) H2 B) adenosine triphosphate C) glycogen D) acetyl~S-CoA 10) Fermentation has a relatively low ATP yield compared to aerobic respiration because: A) less ATP is consumed during the first stage of aerobic catabolism. B) organic substrate used as terminal electron acceptor C) substrate-level phosphorylation yields a lot of ATP. D) more reducing equivalents are used for anaerobic catabolism. From the standpoint of the microorganism, in glycolysis the crucial product is: tion products are waste products.
