Human Bio Unit 2 - Energy Sources Flashcards
What does ATP stand for?
Adenosine trisophate
Formula for respiration
C(6)H(12)O(6) + 6O(6) -> 6CO(2) + 6H(2)O
ATP
Mobile source of energy
Our main source of energy
In order, where can ATP be found in?
Glucose - quickest to be broken down
Fatty acids
Protein - last resort
Information bout fatty acids (where ATP is found)
Triglycerides
Lots of energy but slow
Has to be reconstructed before useful
What is a sign that a cell is active?
Lots of mitochondria
How does ATP work?
Energy comes from phosphate bonds being broken
Equation for ATP use
ATP <–> ADP + P
or
Adenosine -P -P -P <–> Adenosine -P -P + -P
(P = phosphate group)
Aerobic respiration
The one our body tries to maintain
38 ATPs per molecule of glucose
Requires good oxygen supply to the muscles
Aerobic respiration equation
Glucose + oxygen -> CO(2) + H(2)O
Anaerobic respiration
Last reserve energy
Leaves you with oxygen debt
2 ATPs per molecule of glucose
What is anaerobic respiration designed for?
Last burst of energy if being chased by a predator
Oxygen debt
When you have used most of oxygen in the body
Need to take a deep breathe to replenish supplies
Haemoglobin
Carrier of oxygen
Made possible by its quaternary structure
Altitude training
Training at high altitudes increases the amount of haemoglobin in red blood cells
