photosynthesis review

1. what is the chemical formula for photosynthesis?
2. what are the products from the light dependent reactions?
3. during the light dependent reactions atp is made in a large protein called:
4. what organelle in autotrophs houses the machinery for photosynthesis?
5. a major energy - carrying molecule that is important for cellular processes is called....
6. during the calvin cycle, how many molecules of co2 are added in order to make one glucose molecule?
7. organisms that make a product like glucose are:
8. a gas that is a byproduct of photosynthesis is called:
9. during photosynthesis the suns energy is converted into:
10. organisms that cannot make their own food and therefore must consume other organisms?

Explanation:

1. The chemical formula for photosynthesis shows the reactants (water and carbon - dioxide) and products (oxygen and glucose) with light as an energy source.
2. In light - dependent reactions, energy - rich molecules ATP and NADPH are produced along with oxygen gas.
3. ATP is synthesized in the thylakoid membrane in a large protein complex.
4. Chloroplasts in autotrophs contain the machinery for photosynthesis.
5. ATP is a major energy - carrying molecule for cellular processes.
6. In the Calvin Cycle, 6 molecules of CO2 are added to make one glucose molecule.
7. Autotrophs are organisms that produce glucose.
8. Oxygen is a by - product of photosynthesis.
9. During photosynthesis, solar energy is converted into chemical energy in the form of glucose.
10. Heterotrophs are organisms that cannot make their own food and must consume other organisms.

Answer:

1. $6H_2O + 6CO_2+\text{light}

ightarrow6O_2 + C_6H_{12}O_6$

1. ATP, NADPH and oxygen gas
2. Thylakoid membrane
3. Chloroplast
4. ATP
5. 6
6. Autotrophs
7. Oxygen
8. Chemical energy (in glucose)
9. Heterotrophs
