decrease

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is ATP and its role in cellular energetics?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

Explain the role of NADPH in photosynthesis.

Back

NADPH is a reducing agent that provides the electrons needed for the conversion of carbon dioxide into glucose during the Calvin cycle.

Front

What is the significance of the electron transport chain in cellular respiration?

Back

It generates ATP through oxidative phosphorylation by transferring electrons and pumping protons across the mitochondrial membrane.

Front

Describe the Calvin cycle.

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, converting CO2 into glucose using ATP and NADPH.
