Question

light dependent reactions 1. reactant: 2. type of energy: thylakoids 3. product calvin cycle (light independent reactions) 5. reactant 4. type of energy: stroma 6. product 7. type of energy: chemical energy (stce), water. glucose, light, long-term chemical energy (ltce), oxygen, short-term

Explanation:

Step1: Identify Light Dependent Reactions Reactant

Light - dependent reactions in photosynthesis use water ($H_2O$) and light. So the reactant (1) is water ($H_2O$) and light (but mainly water as a chemical reactant, light as energy source).

Step2: Identify Energy for Light Dependent Reactions

The type of energy (2) for light - dependent reactions is light energy (from the sun).

Step3: Identify Product of Light Dependent Reactions

The products (3) of light - dependent reactions are oxygen ($O_2$), ATP (adenosine triphosphate), and NADPH (nicotinamide adenine dinucleotide phosphate).

Step4: Identify Energy Transferred to Calvin Cycle

The type of energy (4) transferred from light - dependent to Calvin cycle is chemical energy in the form of ATP and NADPH.

Step5: Identify Reactant of Calvin Cycle (Light Independent)

The reactant (5) of the Calvin cycle is carbon dioxide ($CO_2$).

Step6: Identify Product of Calvin Cycle

The product (6) of the Calvin cycle is glucose ($C_6H_{12}O_6$) (and other carbohydrates).

Step7: Identify Energy in Calvin Cycle Product

The type of energy (7) in the product (glucose) is chemical energy (stored in the bonds of glucose).

Answer:

1. Reactant (Light Dependent): $H_2O$ (water)
2. Type of Energy (Light Dependent): Light Energy
3. Product (Light Dependent): $O_2$, ATP, NADPH
4. Type of Energy (to Calvin Cycle): Chemical Energy (ATP, NADPH)
5. Reactant (Calvin Cycle): $CO_2$ (carbon dioxide)
6. Product (Calvin Cycle): $C_6H_{12}O_6$ (glucose)
7. Type of Energy (Product): Chemical Energy
