1. What two molecules are formed when a phosphate is removed from ATP?

There are three phosphate groups in ATP molecule (Adenosine Triphosphate), when removing one phosphate molecule, ADP molecule is formed (Adenosine Diphosphate).

2. What is the function of ATP? Describe the molecule.

The function of ATP is storing energy within a cell. ATP is adenosine triphosphate, C10H16N5O13P3, a high energy complex, giving the necessary power to push metabolistic reactions in the body. Its composed of adenosine, a ribose sugar, and three phosphates.

3. Describe how ADP is converted into ATP.

By adding one phosphate molecule to ADP, it becomes ATP.

What are they?

Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture light energy and utilize it to make energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use ATP and NADPH to capture and reduce CO2.

5. State the four factors that must be present to begin the process of photosynthesis.

Chloroplasts, H2O, sunlight, CO2.

6. Summarize the events of the light reactions.

Light Reactions of Photosynthesis:

Electrons flow to NADP

Split Water

Pump Protons

ATP Production

7. What are the products of the light reactions?


8. In what part of the chloroplast do the light reactions take place?

Thylakoid membranes of the chloroplasts.

9. Where in the chloroplast is chlorophyll located?

Chlorophyll molecules are embedded in the thylakoid membranes.

l0. What is the term for the stacks of disks seen in plants?

Grana for plural / Granum for singular.

11. What is the term for the fluid surrounding these stacks?

Stoma, is the fluid matrix that surrounds the thylakoids.

I2. What function is served by chlorophyll?

Chlorophyll is a molecule that absorbs light and synthesizes it into the energy, in turn giving plants life. Chlorophyll is primarily responsible for the photosynthesis process and hence performs as the basic building block of all life. It also gives plants
