through Respiration, is used in
photosynthesis and returns to respiration.
• Your story should be
– Very detailed
– Explain the processes
– It will be more than a few sentences!!!
6.1 – Energy for Cells
ATP – adenosine triphosphate
What is ATP?
Free Energy = energy available to do work.
endergonic reactions = reactions that absorb energy
exergonic reactions = reactions that release energy

Autotrophs – Produces its own Energy / Food
Heterotrophs – get energy from the food they consume
Jan Van Helmont = Plants gained mass from water
Joseph Priestley = 0xygen released by plants ( candle
experiment)
Jan Ingenhousz = Oxygen was released during the day / Light
Plant produced bubbles.
Julius Robert Mayer – Light energy was converted to chemical
energy.
Melvin Calvin = Calvin Cycle – Path of carbon to form
glucose
Energy Laboratory
Reminders:
1. The tip of the flame is the hottest. Make sure the test tube is relatively close to
the tip of the flame.
2. Make sure you use the tip of the flame from the match to light the nut.
3. 1ml of water = 1 gram
When you find the calories for your peanut look at the weight.
if its .5 (half) a gram then you need to divide it by the calories to find out the total
calories per gram of nut.
Example:
1. If my peanut is .5g then the calories from that nut is only half of what a full gram
would give me therefore the calories/g would be more than the experimental
value.
If the calories from the experiment = 100c Then the calories per gram = 200c/g
100c / .5g = 200 c/g
2.
If my peanut is 1.5g then the calories from that peanut is more than what a full
gram would give me therefore the calories/g would be less than the experimental
value
If the calories form the experiment =100c Then the calories per gram = 66c/g
100c / 1.5g = 66.66 c/g
