|
what is catabolism?
|
breakdown of larger molecules into smaller molecules, with the release of energy.
|
|
|
what is anabolism?
|
synthesis of larger molecules from smaller molecules, using energy.
|
|
|
what is metabolism?
|
the sum of all chemical processes to maintain the body.
|
|
|
what is metabolic rate dependent on?
|
the level of a person's activity.
|
|
|
what is the metabolic rate in skeletal muscle?
|
it can increase up to 50 times from resting to maximal exercise.
|
|
|
carbohydrate facts
|
(CHO) - preferred source of fuel
Used as glucose in the body for an energy source Stored as Glycogen Requires less oxygen to get the energy Store about 1500 kcal |
|
|
fats facts
|
– long term fuel
Used as fatty acids in the body for an energy source More energy in fats but takes more oxygen to get energy out. Store about 72,000 kcal |
|
|
protein facts
|
- primarily build new tissue (limited use as a fuel)
Made from amino acids Structural and functional Less then 5% of metabolism |
|
|
what is ATP (adenosine phosphate)?
|
The basic biological form of energy used by cells
Breaking the high energy bond within ATP releases energy for cellular work….. ATP is the main source of energy |
|
|
what are the three types of energy systems?
|
1) ATP- PCr system (immediate)
2)Anaerobic system (Lactic Acid system) 3)Aerobic system (Oxidative System) |
|
|
anaerobic system details?
|
Its quick like a "KICK" of energy but produces very small amounts of ATP
|
|
|
aerobic system details?
|
It is very slow but it produces lots of ATP.
|
|
|
how many ATP is made using anaerobic glycolysis?
|
2 when using glucose
3 using glycogen |
|
|
how many ATP is made using aerobic glycolysis?
|
36-38 ATP
|
|
|
what is the Kreb cycle?
|
metabolic process where pyruvate is metabolized as well as CHO, fat and protein.
H+ released during Kreb’s are taken to Electron Transport Chain ADP rephosphorylated to ATP |
