Exam Questions and CORRECT Answers
bioenergetics - CORRECT ANSWER - flow of energy in a biological system, concerns
primarily the conversion of macrontrients - carbs, proteins, and fats, which contain chemical
energy


catabolism - CORRECT ANSWER - breakdown of large molecules into smaller molecules



anabolism - CORRECT ANSWER - building up process of small molecules into larger
molecules


exergonic reactions - CORRECT ANSWER - catabolic, energy releasing reactions



endergonic reactions - CORRECT ANSWER - anabolic, require energy, contraction of
muscle type reactions


ATP hydrolysis - CORRECT ANSWER - the breakdown of 1 ATP to yield energy



myosin ATPase - CORRECT ANSWER - enzyme that catalyzes ATP hydrolysis for cross-
bridge recycling


calcium ATPase - CORRECT ANSWER - enzyme responsible for hydrolyzing ATP to
pump calcium into the sarcoplasmic reticulum


sodium-potassium ATPase - CORRECT ANSWER - enzyme responsible for maintaining
the sarcolemmal concentration gradient after depolarization occurs


ATP hydrolysis reaction - CORRECT ANSWER - ATP+H20 <----> ADP+P+H+Energy

,ATP - CORRECT ANSWER - What is the energy source for muscle action?



phosphagen system - CORRECT ANSWER - Which system provides ATP short term?



Phophagen system - CORRECT ANSWER - What is active at the start of all exercise
regardless of intensity?


Phosphagen system - CORRECT ANSWER - System involving hydrolysis of ATP and
breakdown of creatine phosphate (CP or can be called phosphocreatine or PCr) with creatine
kinase reaction enzyme


creatine kinase - CORRECT ANSWER - enzyme that catalyzes the synthesis of ATP from
CP and ADP


80-100 g (about 3 ounces) - CORRECT ANSWER - How many grams (or ounces) of ATP
does the body store at any given time?


False, ATP stores cannot be completely depleted - CORRECT ANSWER - ATP stores can
be completely depleted due to the necessity for basic cellular function. True or False?

circumstances, skeletal muscle concentrations of _____ are four to six times higher than _____
concentrations (ATP/CP)


Type II muscle fibers contain higher concentration of CP than Type I fibers. - CORRECT
ANSWER - Type ___ muscle fibers contain higher concentration of CP than Type ___
fibers (Type I/Type II)


adenylate kinase (also called myokinase) reaction - CORRECT ANSWER - single enzyme
reaction that can rapidly replenish ATP
2ADP <----> ATP+AMP

, glycolysis - CORRECT ANSWER - AMP is a poweful stimulant of ______ system



Law of mass action or mass action effect - CORRECT ANSWER - What states that the
concentrations of reactants or products (or both) in solution will drive the direction of the
reactions?

(carbohydrates, fat or protein) to resynthesize _____ (ADP/ATP)?


glycogen stores in the muscle or glucose delivered in the blood - CORRECT ANSWER -
Where do the carbohydrates come from for glycolysis?


phosphagen - CORRECT ANSWER - Is ATP resynthesis rate faster during phosphagen or
glycolysis?


near-equilibrium reactions - CORRECT ANSWER - Reactions that proceed in the
direction dictated by the concentrations of the reactants due to the law of mass action


In the sarcoplasm - CORRECT ANSWER - Where does phosphagen occur?



In the sarcoplasm - CORRECT ANSWER - Where does glycolysis occur?



Pyruvate - CORRECT ANSWER - What is the end result of glycolysis?


Converted to lactate for fast glycolysis or sent to mitochondria for slow glycolysis - CORRECT
ANSWER - What two ways can pyruvate go after glycolysis?



Pyruvate is primarily converted to lactate - CORRECT ANSWER - How is pyruvate used
during resistance training?
