Chapter 2 - Vocabulary Flashcards
(11 cards)
Metabolism
The total of an energy transformations that occur in the body. (Carbohydrates, Fats, and Proteins)
ATP
Adenosine triphosphate
Stored chemical energy that links the energy-yielding and energy-requiring functions within all cells.
3 Processes (All three are active at all times, one may have dominance)
- ADP + PC (phosphocreatine) > C + ATP (ATP PC System)
- Anaerobic respiration-glycolysis (Lactic Acid System)
- Aerobic respiration- glycolysis, Krebs cycle, ETS/OP (Aerobic System)
Coupled Reactions
Energy-requiring and Energy-releasing
Cellular Respiration
The process by which cells transfer energy from food to Tap in a stepwise series of reactions; relies heavily upon the use of oxygen
Cells utilizing energy
Anaerobic
In the absence of oxygen
Aerobic
In the presence of oxygen
Glycogenolysis
The process by which stored glycogen is broken down (hydrolyzed) to provide glucose
Glycolysis
The energy pathway responsible for the initial catabolism of glucose in a 10 or 11 step process that begins with glucose or glycogen and ends with the production of pyruvate (aerobic glycolysis) or lactate (anaerobic glycolysis)
Gluconeogenesis
The creation of glucose in the liver from noncarbohydrate sources, particularly glycerol, lactate, pyruvate , and alanine.
-Glu: glucose Neo: new Genesis: creation
Beta Oxidation
Cyclic series of steps that breaks off successive pairs of carbon atoms fro FFA (Free-Fatty Acids) , which are then used to form Acetyl CoA
- Energy Dense
- 9 kcal/oz of fat
- Body stores fat in muscles and adipose tissue
- Fat is stored DRY (no water molecules)
AMP
Adenosine Monophosphate
