Energy Transfer

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose using carbon dioxide and water, releasing oxygen as a byproduct.

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. It occurs in both aerobic and anaerobic conditions.

Front

What is ATP?

Back

Adenosine triphosphate (ATP) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What happens when ATP loses a phosphate group?

Back

When ATP loses a phosphate group, it releases energy that can be used for cellular work, converting it into adenosine diphosphate (ADP).

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must obtain energy by consuming other organisms.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food through photosynthesis or chemosynthesis, while heterotrophs obtain energy by consuming other organisms.

Front

What is chemiosmosis?

Back

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient, often associated with the production of ATP.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.
