Unit 5 Cellular Energy Photosynthesis

Front

What is the purpose of PHOTOSYNTHESIS?

Back

To make sugar for cells.

Front

What are enzymes?

Back

These are proteins that act as biological catalysts.

Front

What is an organelle?

Back

These are 'organs' for the cell, they carry out important functions of life.

Front

What powers the ATP Synthase protein to turn ADP into ATP?

Back

Hydrogen ions (H+).

Front

What is NADPH?

Back

A molecule that moves electrons, important for making ATP (its precursor is NAD+).

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert CO2 and water into glucose.

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

In the chloroplasts.

Front

What is the significance of ATP in cellular processes?

Back

ATP serves as the energy currency of the cell, providing energy for various biochemical reactions.
