8.Metabolism

CATEGORY:

•Metabolic Pathway

DEFINITION:

•Set of life sustaining chemical transformations within cells allowing growth & maintenance, reproduction and response to environment

FUNCTION:

•Converts consumed nutrients to Adenosine Triphosphate (ATP)...the fuel used in muscular activity

ACTIONS:

•ATP produced with (aerobic) or without oxygen (anaerobic)

•Catabolic - breaking down

•Anabolic - building up

FACTS:

•Disease often caused by an imbalanced Metabolism

•Three types of essential molecules for biological function are...

-Amino Acids...Proteins

-Carbs...Starch, Glucose, Cellulose (vegetables)

-Lipids...Fats

MANIPULATION:

•Anaerobic pathway increases need for oxygen after workout (EPOC)

•Anaerobic activity uses stored ATP as first form of fuel

DIETING:

•Metabolic Rate (BMR) influences how much food/fuel is required and food/fuel is obtained

•Amino Acids are a source of Carbon, especially when Glucose is scarce

•5-8min warmup required to efficiently use Aerobic metabolism to produce ATP - once steady state of oxygen consumption achieved, this pathway provides energy

RELATED TO:

•Macro and Micro Nutrients

•ATP

HOMEOSTASIS:-

•State where variables are regulated so that internal conditions remain stable and relatively constant

-Metabolic...energy regulation

-Hormonal...hormone regulation
