Complete Questions And Correct Answers(Verified
Answers)|Already Graded A+
Specifics of catabolic reactions: - CORRECT ANSWER--Degrative reactions that
break down cellular components (ex: digests good)
-Exergonic (releases energy)
-Involves hydrolysis of macromolecules or biological or biological oxidation
-Procedes aerobically or anaerobically
-Products may become building blocks
Specifics of anabolic pathways - CORRECT ANSWER--Synthetic reactions that build
up cellular components (glycogen, muscle proteins, etc.)
-Enderonic (require energy)
Obligate aerobes - CORRECT ANSWER-An absolute requirement for oxygen
Obligate anaerobes - CORRECT ANSWER--Cannot use oxygen
-Oxygen may be toxic to these organisms
-some types of bacteria
,Metabolism - CORRECT ANSWER-Chemical reactions that occur within a cell
Metabolic pathways - CORRECT ANSWER-A series of chemical reactions each of
which accomplishes a specific task
Two types of metabolic pathways: - CORRECT ANSWER-Catabolic and anabolic
Strict anaerobes - CORRECT ANSWER-Oxygen is toxic
Facultative organisms - CORRECT ANSWER--Can function under either aerobic or
anaerobic conditions (can switch between oth based on o2 availability)
-Includes some types of arterial or fungi
ATP - CORRECT ANSWER-The molecule commonly used to store energy for
cellular work
Energy is released by breaking one phosphoanhydride bonds of ATP. What are the
products? - CORRECT ANSWER-ADP and inorganic phosphate
Chemotrophic energy metabolism and types of metabolic reactions: - CORRECT
ANSWER-Pathways by which cell catabolize nutrients and conserve the released
energy in ATP
-Oxidative (removal of electrons)
, -Reduction (Addition of electrons)
-Hydrogenation (addition of protons)
-Dehydrogenation- (removal of protons)
Reaction coupling: - CORRECT ANSWER--Oxidation often includes dehydrogenation
-Reduction often includes hydrogenation
T/F NADH+ is a coenzyme - CORRECT ANSWER-True
There is no O2 required in the oxidation of glucose (T/F) - CORRECT ANSWER-True
The main energy source for most cells in the body: - CORRECT ANSWER-Glucose
Glycolysis - CORRECT ANSWER-The 10-step reaction for the metabolism of
glucose. No O2 present
Products of glycolysis: - CORRECT ANSWER-4 ATP
2 Pyruvate
The fate of pyruvate depends on: - CORRECT ANSWER-The presence/absence of
o2
