Unit 3 Study Guide: Energy Flow 24-25

Front

Define the term: Grana.

Back

Grana are stacks of thylakoids in chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

Is ADP or ATP more like a fully charged battery, and why?

Back

ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.

Front

Which bond on ATP is the easiest to break to release stored energy?

Back

The bond between the second and third phosphate.

Front

In what process does ATP get created?

Back

Cellular respiration.

Front

What is the primary function of ATP in cells?

Back

ATP serves as the main energy currency of the cell, providing energy for various cellular processes.

Front

What are the two main types of cellular respiration?

Back

Aerobic respiration and anaerobic respiration.

Front

What is photosynthesis?

Back

Photosynthesis is 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 is a pigment that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use ATP and NADPH to synthesize glucose.
