Energy and Life

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells. It consists of adenine, ribose, and three phosphate groups.

Front

What is ADP?

Back

ADP (Adenosine Diphosphate) is a molecule that is formed when ATP loses one phosphate group. It consists of adenine, ribose, and two phosphate groups.

Front

What is the difference between ATP and ADP?

Back

ATP has three phosphates; ADP has two.

Front

What does the 'TP' in ATP stand for?

Back

The 'TP' in ATP stands for tri (3) phosphates.

Front

What is the primary function of ATP in cells?

Back

ATP provides energy for various cellular processes, including active transport.

Front

What are autotrophs?

Back

Autotrophs are organisms that can capture energy from sunlight or inorganic compounds to produce their own food.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is active transport?

Back

Active transport is the process by which cells move substances against their concentration gradient, requiring energy from ATP.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment in plants that captures sunlight, allowing for the conversion of light energy into chemical energy.

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.
