Energy in Living Things

Front

What is the primary function of ATP in cells?

Back

ATP (Adenosine Triphosphate) primarily functions to store and provide energy for cellular processes.

Front

What reaction demonstrates the release of energy in cellular processes?

Back

ATP 🡪 ADP + P (Adenosine Triphosphate is converted to Adenosine Diphosphate and inorganic phosphate, releasing energy.)

Front

Where does the Calvin cycle occur in plant cells?

Back

The Calvin cycle takes place in the stroma of the chloroplast.

Front

What are organisms called that produce their own food using sunlight?

Back

Organisms that use energy from the sun to make their own food are called producers.

Front

What is the gel-like substance surrounding the grana in chloroplasts?

Back

The gel-like material surrounding the grana is called stroma.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs sunlight, providing the energy needed for photosynthesis.

Front

What is the difference between producers and consumers in an ecosystem?

Back

Producers create their own food through photosynthesis, while consumers obtain energy by eating other organisms.

Front

What is the process by which plants convert sunlight into chemical energy?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle.

Front

What is the significance of the stroma in chloroplasts?

Back

The stroma is the site of the Calvin cycle, where carbon fixation occurs and sugars are synthesized.
