1. ATP-ADP Cycle

2. Heterotrophs Autotrophs But first…..
Can NOT make own food… they get their energy by the foods they eat
Make their own food
with light – phototrophs
with chemicals -- chemotrophs

3. ATP Adenosine triphosphate P JOB--- store & release energy + ribose -
adenine P
ribose + -

4. ADP Adenosine diphosphate P
JOB--- energy can be stored by adding another Phosphate.. and becoming ATP
Adenosine diphosphate + -
adenine P
ribose

5. ATP ADP P P + + Releasing energy Storing energy - - Releasing energy
adenine P
ribose
Releasing energy
adenine P
ribose
Storing energy

6. ATP-ADP Cycle
ATP – ADP Cycle
phosphate removed

7. HEAT Transformation of Energy Energy is the ability to do work.
Thermodynamics is the study of the flow and transformation of energy in the universe.
Laws of Thermodynamics
First law - Energy can be converted from one form to another, but it cannot be created nor destroyed.
Second law - Energy cannot be converted without the loss of usable energy.
HEAT

8. Carbohydrates Lipids Proteins most commonly broken down to make ATP.
not stored in large amounts
up to 36 ATP from one glucose molecule
Lipids
store the most energy.
80% of energy in your body
About 146 ATP from a triglyceride
Proteins
least likely to be broken down to make ATP.
amino acids not usually needed for energy
about the same amount of energy as a carb.

10. Using Biochemical Energy
1) Movement in cell
2) Protein synthesis
3) Active Transport
(Low to high concentration across membrane)
