Energy & Enzymes
A type of protein that catalyzes chemical reactions.
What is an enzyme?
The product synthesized from metabolic energy systems that stores and releases energy to do work.
What is Adenosine Triphosphate (ATP)?
The general location of oxidative metabolism.
What is the mitochondria?
The location carbohydrates begin to digest.
What is the oral cavity (mouth)?
The 2 primary factors that inhibit exercise.
What is intensity and duration?
An enzyme that can add or remove a phosphate.
What is a kinase?
The location of anaerobic energy systems?
What is the sarco/cyto-plasm?
The component of the oxidative system that does not yield ATP directly, but rather elements to create ATP.
What is the Krebs Cycle?
The location fats begin to digest.
What is the upper portion of the small intestine?
The name given to the point at which a person shifts from predominantly fat oxidation to carb oxidation during exercise.
What is the crossover point?
A type of enzyme that can rearrange molecular structures, but does not add or remove any elements.
What is an isomerase?
The net total of ATP from a single molecule of glycogen.
What is 3 ATP?
The electron transporters provided by the Krebs cycle.
What is NADH and FADH2?
The enzyme that initiates carb digestion.
What is amylase?
The metabolic by-products of the anaerobic systems that inhibit exercise performance.
What is inorganic phosphate (Pi), hydrogen (H+), and lactate (La+)?
The name given to an enzyme that can slows overall reactions, prevents runaway reactions, and occurs early in a biochemical pathway.
What is a Rate Limiting Enzyme?
The RLE of the ATP-PCr system.
What is creatine kinase?
The protein complex that a NADH redox reaction occurs in the Electron Transport Chain.
What is Complex I?
The process of breaking down lipids stored as tryglycerides.
What is lipolysis?
The intensity/type of exercise that depletes glycogen from predominantly type II muscle fibers.
What is high intensity exercise?
The name given to reactions that release energy.
What is an exergonic reaction?
The RLE of glycolysis.
What is phosphofructokinase (PFK)?
The compound Acetyl-CoA combines with to enter and initiate the Krebs Cycle.
What is oxalacetate?
The process of converting free fatty acids (FFA) into 2, 2-carbon molecules of Acetyl-CoA.
What is beta-oxidation?
The Respiratory Exchange Ratio (RER) that indicates 100% of whole-body energy metabolism is coming from carb oxidation.
What is 1.0?
