Front

What factor affects the rate of photosynthesis as shown in the graph?

Back

Temperature

Front

What is the final electron acceptor at the end of the Electron Transport Chain?

Back

Oxygen

Front

Which Photosystem is temporarily shut down during Cyclic Electron Flow?

Back

Photosystem II

Front

What is the biological importance of lactic acid fermentation?

Back

To regenerate NAD+ so that glycolysis can continue.

Front

Which of the following is not a product of photosynthesis?

Back

CO2

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 the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin cycle (light-independent reactions).

Front

What is glycolysis?

Back

The metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What is the main purpose of the Krebs cycle?

Back

To produce electron carriers (NADH and FADH2) for the Electron Transport Chain.
