Final Exam study guide 23

Front

What is ATP and what role does it play in a cell?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

Is glucose a reactant in cellular respiration?

Back

Yes, glucose is a reactant in cellular respiration, where it is broken down to produce ATP.

Front

What process do consumers use to release ATP from the macromolecules they consume?

Back

Consumers release ATP through cellular respiration, not photosynthesis.

Front

In which trophic level are producers found?

Back

Producers are found in trophic level D, as they are the primary source of energy in an ecosystem.

Front

Where does all the energy on Earth originate?

Back

All the energy on Earth comes from the sun, which is harnessed by producers through photosynthesis.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the difference between photosynthesis and cellular respiration?

Back

Photosynthesis converts solar energy into chemical energy (glucose), while cellular respiration converts glucose into usable energy (ATP).

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are ATP, carbon dioxide, and water.

Front

What is the role of producers in an ecosystem?

Back

Producers convert sunlight into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is the significance of ATP in cellular processes?

Back

ATP provides the necessary energy for various cellular activities, including muscle contraction, nerve impulse propagation, and biosynthesis.
