Question

question 1

1. in photosynthesis, what are the two major reactions that take place? select all answers that apply.

light dependent reactions
light independent reactions
electron transport chain
krebs cycle
question 2

1. true or false: photosynthesis uses sunlight to make carbohydrates(sugar).

true
false

Explanation:

• For Question 1: Photosynthesis consists of two main stages. The light - dependent reactions (which require light) convert light energy into chemical energy (ATP and NADPH). The light - independent reactions (Calvin cycle) use the products of the light - dependent reactions to fix carbon dioxide and produce carbohydrates. The electron transport chain is part of the light - dependent reactions but is not one of the two major reactions. The Krebs cycle is part of cellular respiration, not photosynthesis.
• For Question 2: Photosynthesis is the process by which plants (and some other organisms) use sunlight, carbon dioxide, and water to produce carbohydrates (sugars) and oxygen. The light - dependent reactions capture sunlight energy, and the light - independent reactions use that energy (in the form of ATP and NADPH) to make sugars from carbon dioxide.

Answer:

1. Light Dependent Reactions, Light Independent Reactions
2. True
