1. Aerobic Cellular Respiration

2. Where do autotrophs get their food?

4. Where do heterotrophs (like you!) get their food?

6. How is the energy in food measured?
In calories! (lower case ‘c’)
A calorie is the amount of energy required to raise the temperature of one GRAM of water one degree Celsius
The ‘calories’ you see on food labels are actually KILOcalories (‘upper case C)
One C = 1,000 c

25. Anaerobic Respiration

26. Two types:
Lactic acid fermentation

27. 2. Alcoholic fermentation

28. What about other molecules we eat? Do they provide any energy?
Proteins
Lipids
Nucleic acids

29. So, we’ve been talking about how organisms extract energy from glucose…..so…..
WHERE DID THE ENERGY IN THE GLUCOSE COME FROM?
And how did the sun’s energy get captured in glucose molecules?
