Quiz 3: How Do Plants Work?
Jan Baptista's experiments showed:
- loss of soil mass < gain of plant mass - gain of plant mass related to water
Priestly's experiments explained:
- plants are associated with O2 - animals require O2
Concerning carbohydrates:
- they all contain C, O, H - the ratio of H to C is fixed at 2:1
What is the equation for photosynthesis?
6CO2 + 6H2O -----> C6H12O6 + 6O2
A chemical energy compound with two phosphate groups found in living cells
ADP
the high energy chemical compound that provides energy
ATP
What is the molecule for glucose?
C6H12O6
What is the reaction for cellular respiration?
C6H12O6 +6O2 = 6CO2 + 6H2O + energy for ATP
