Photosynthesis: An Overview

Multiple Choice

What is the role of ATP in cellular processes?

• It stores energy for later use

• It transfers energy from food breakdown to cell processes

• It is a type of food

• It is not involved in energy transfer

Multiple Choice

What does ATP become whenever energy is released?

• The molecule is completely used up.

• An adenine, ribose, and two phosphates attached together.

• Nothing changes and it remains Adenosine Triphosphate.

• ATP breaks into its three main parts.

Multiple Choice

What is the role of chlorophyll in photosynthesis?

• To absorb sunlight

• To release oxygen

• To capture carbon dioxide

• To produce glucose

Multiple Choice

What do pigments do?

• Absorb specific wavelengths(color) of visible light for energy.

• Absorb CO₂ in the Stroma to create sugar.

• Transports e^- in the electron transport chain.

• Transports energy between plant cells.

Multiple Choice

What is the role of NADPH in the process of electron transport?

• To accept high-energy electrons

• To release energy as heat

• To transfer electrons to chlorophyll

• To store energy in glucose

Multiple Choice

Imagine you're a scientist studying photosynthesis in plants. You're particularly interested in the phase where light energy is converted into chemical energy. In which part of the chloroplast does this light-dependent reaction occur?

• Stroma

• Thylakoid membrane

• Outer membrane

• Inner membrane

Multiple Choice

Where does the carbon dioxide come from that goes into the plant for photosynthesis?

• from the ground through the roots

• "inhales" through the stomata

• from the petals of the flower

• makes it internally
