- to convert solar energy to usable chemical energy and store that energy in sugar molecules
- provides organisms with organic carbon
Photosynthesis is a __, not a __.
- biochemical process
- chemcial reaction
In brief, it links __ and __ using energy from __ that has temporarily been stored in two differnet high energy compounds.
The overall effect of photosynthesis is the reverse of __.
aerobic cell resp
Which molecule is energy poor and which is energy rich
- co2 is energy poor
- glucose is energy rich
Phyotosynthesis is the ultimate energy source for almost all organisms. Those organisms that cannot use sunlight directly must rely on photosynthetic organisms directly or indirectly for a source of energy and organic carbon.
In addition to the major product of photosynthesis, __, __ is also produced. Photosynthesis is the source of __ that is used in CR
- energy rich glucose
- O2 in the air
The entire process of phtosynthesis, starting with CO2 and H2o and ending with glucose, occurs in two main parts or phases
- photophosphorylation (light reactions)
- Calvin Cycle (dark reactions)
Purpose of photophosphorylation?
to trap light energy, convert it to chemical energy and store it temporarily in molecules
Purpose of Calvin cycle
to use chemical energy stored in ATP and NADPH produced in photophosphorylation to reduce CO2 to sugar, enabling organism to store that energy long-term
Therefore, __ and__ link the light and dark reactions.
Both stages of photosynthesis occur in __.
