Using the photosynthesis model, consider each of the statements. Choose ALL of the statements that correctly describe photosynthesis.
Responses
A Oxygen is a product.Oxygen is a product.
B Glucose is a product.Glucose is a product.
C Oxygen is a reactant.Oxygen is a reactant.
D Carbon dioxide is a product.Carbon dioxide is a product.
E Carbon dioxide is a reactant.
The correct statements that describe photosynthesis are:
A. Oxygen is a product.
B. Glucose is a product.
E. Carbon dioxide is a reactant.
A - Oxygen is a product.
B - Glucose is a product.
E - Carbon dioxide is a reactant.
To determine which statements correctly describe photosynthesis, it is helpful to understand the process of photosynthesis. Here's a breakdown of the steps involved in photosynthesis:
1. Photosynthesis occurs in the chloroplasts of plant cells, specifically in the chlorophyll-containing organelles called thylakoids.
2. The primary reactants involved in photosynthesis are carbon dioxide (CO2) and water (H2O).
3. In the presence of sunlight, chlorophyll absorbs energy and initiates a series of chemical reactions.
4. During the light-dependent reactions, water molecules are split, releasing oxygen (O2) as a byproduct.
5. These reactions also generate high-energy molecules such as ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are used in the next stage.
6. In the light-independent reactions (also known as the Calvin cycle), ATP and NADPH are used to convert carbon dioxide (CO2) into glucose (C6H12O6). Glucose is a sugar and serves as a primary energy source for plants.
Now, let's analyze each statement using the information provided:
A) Oxygen is a product. - Correct: Oxygen is released as a byproduct during the light-dependent reactions of photosynthesis.
B) Glucose is a product. - Correct: Glucose is produced during the light-independent reactions (Calvin cycle) of photosynthesis.
C) Oxygen is a reactant. - Incorrect: Oxygen is not a reactant in photosynthesis. It is produced as a byproduct.
D) Carbon dioxide is a product. - Incorrect: Carbon dioxide is not a product of photosynthesis; it is a reactant that is converted into glucose.
E) Carbon dioxide is a reactant. - Correct: Carbon dioxide acts as a necessary reactant in the process of photosynthesis.
Therefore, the correct statements are:
A) Oxygen is a product.
B) Glucose is a product.
E) Carbon dioxide is a reactant.
