Module 4 - Terminology Flashcards
What does Anaerobic refer to?
Refers to the lack of oxygen utilization rather than the absence of oxygen.
What is Adenosine Triphosphate?
A molecule responsible for storing and releasing energy in the body. ATP is generated in the mitochondria of cells and can be produced both aerobically and anaerobically.
What is Mitochondria?
An organelle that is the power plant of cells - it converts potential energy from food molecules into ATP
What is Glucose?
A simple sugar in the blood
What is Glycogen?
The main form of carbohydrate storage in the body and can be converted to glucose
Glycolysis
The metabolism of glucose - A process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen
What is Pyruvate?
An acid that is the result of glycolysis.
What is the Kerbs cycle?
A cycle of complex chemical reactions that cells go through in the presence of oxygen to create energy (cellular respiration). They are also referred to as the citric acid cycle.
What is Lactate?
A substance found in body tissue and a by-product of pyruvate
Lactate threshold
The lactate threshold is a point during exhaustive, all-out exercise at which lactate builds up in the bloodstream faster than the body can remove it
Maximum Lactate Steady State (MLSS)
Maximal lactate steady state occurs when lactate accumulation equals lactate clearance in the body during exercise.
Onset of blood lactate accumulation
OBLA is the point at which lactate begins to accumulate in the blood at an accelerated rate.
Acetyl-CoA
A molecule that results from the oxidation of fatty acid, amino acid, and pyruvate. Acetyl-CoA is broken down and used for energy production in the kerbs cycle.
Creatine Phosphate (CP)
A high energy phosphate compound that aids in the resynthesis or regeneration of ATP
Ventilatory Threshold (VT)
The point at which the ventilation rate increases faster than the workload.
