8.1 Concept Check

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a compound used by cells for the storage and release of energy; it consists of adenine, ribose, and three phosphate groups.

Front

What is ADP?

Back

ADP (Adenosine Diphosphate) is a molecule that has two phosphate groups and stores less energy than ATP.

Front

What is a Heterotroph?

Back

A Heterotroph is an organism that obtains food by consuming other living things.

Front

What is Photosynthesis?

Back

Photosynthesis is the process by which plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.

Front

What is an Autotroph?

Back

An Autotroph is an organism that makes its own food.

Front

What is the role of ATP in cellular processes?

Back

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

Front

How do Heterotrophs obtain energy?

Back

Heterotrophs obtain energy by consuming other organisms, either plants or animals.

Front

What is the significance of Photosynthesis in the ecosystem?

Back

Photosynthesis is crucial for the ecosystem as it produces oxygen and organic compounds that serve as food for heterotrophs.

Front

What are the main components of ATP?

Back

The main components of ATP are adenine, ribose (a sugar), and three phosphate groups.

Front

What is the difference between ATP and ADP?

Back

ATP has three phosphate groups and stores more energy, while ADP has two phosphate groups and stores less energy.
