Question

Accepted Answer

### Question 5
# Explanation:
## Step1: Recall photosynthesis energy conversion
Photosynthesis converts solar energy to chemical energy stored in chemical bonds of carbohydrates (like glucose).
## Step2: Analyze options
- Option A: Energy is stored in chemical bonds of carbohydrates (e.g., glucose) from photosynthesis.
- Option B: $CO_2$ and $H_2O$ are reactants, not energy storage.
- Option C: Enzymes catalyze reactions, not store energy.
- Option D: Chlorophyll absorbs light, not store energy from sun as chemical bonds.
# Answer: A. chemical bonds in carbohydrates

### Question 6
# Explanation:
## Step1: Recall energy-absorbing molecule in photosynthesis
Chlorophyll is the pigment that absorbs sunlight energy for photosynthesis.
## Step2: Analyze options
- Option A: ATP is energy currency, not for absorbing sunlight.
- Option B: ADP is low-energy form, not for absorption.
- Option C: Chlorophyll absorbs light energy.
- Option D: Glucose is a product, not for absorbing sunlight.
# Answer: C. chlorophyll

### Question 7
# Explanation:
## Step1: Recall photosynthesis products
Photosynthesis produces glucose (and $O_2$) from $CO_2$ and $H_2O$ using light energy.
## Step2: Analyze options
- Option A: Glucose is a product (stored energy).
- Option B: Light energy is input, not product.
- Option C: $CO_2$ is a reactant.
- Option D: $H_2O$ is a reactant.
# Answer: A. glucose

### Question 8
# Explanation:
## Step1: Recall light-dependent reactions (water splitting)
In light-dependent reactions, water ($H_2O$) is split into $O_2$ (released) and $H^+$ (used to make NADPH).
## Step2: Analyze options
- Option A: $H_2O$ split releases $O_2$ (not $H_2$), and $H$ is used for NADPH, $O_2$ is released. Wait, correction: Water splits into $O_2$ (released) and $H^+$ (used in electron transport to make NADPH). The Calvin cycle uses $CO_2$ and energy (ATP, NADPH) to make glucose. Wait, re - analyze:
- Option A: Incorrect (water splits into $O_2$, not $H_2$ released).
- Option B: $O_2$ is released, $H$ from water is used to create NADPH (correct as per light - dependent reactions: $H_2O$ → $O_2$ (released) + $H^+$ (used in electron transport to form NADPH, which is used in Calvin cycle)).
- Option C: $H$ and $O$ are not both released as byproducts (only $O_2$ is released, $H$ is used).
- Option D: $H$ and $O$ atoms are not transported via electron transport chain as atoms, but electrons and protons are involved.
# Answer: B. Oxygen is released to the atmosphere, and hydrogen is used to create NADPH.
