ATP and Energy Acquisition

Flashcards covering the key concepts related to ATP, energy acquisition, and the role of different organisms in the ecosystem.

What is ATP?

ATP is an energy-carrying molecule that carries and stores energy for cell functions.

What is the main purpose of ATP?

The main purpose of ATP is to serve as the main energy currency for the cell.

What are the components of ATP?

ATP consists of Adenine, Ribose, and Phosphates.

What happens during the ATP-ADP cycle?

A lot of energy is stored in the bond between the last two phosphates; energy is released when a phosphate group is removed, and ADP is recycled to form ATP when a phosphate group is added.

What energy is released when a phosphate group is removed from ATP?

Energy is released for cell processes, coming from broken down food.

Why is breaking down ATP considered an exothermic process?

Breaking down ATP is considered exothermic because more energy is given off than required.

Why is forming ATP considered an endothermic process?

Forming ATP is considered endothermic because energy is taken in.

Define Producer.

Producers are organisms that capture energy during photosynthesis and get energy from nonliving sources.

Define Consumer.

Consumers are organisms that get energy from living or once living sources.

What is the role of Detritivores?

Detritivores, or decomposers, eat dead animals.

What do Carnivores eat?

Carnivores eat only meat.

What is an Omnivore?

An omnivore is an organism that eats both meat and vegetation.

Define Herbivore.

Herbivores are organisms that eat only vegetation.

How do autotrophs acquire energy?

Autotrophs acquire energy during photosynthesis to make simple sugars.

How do heterotrophs acquire energy?

Heterotrophs acquire energy by eating other organisms.

What is the significance of detritivores in a food chain?

Detritivores are significant in a food chain/web because they eat dead animals and play a crucial role as decomposers.
