Biology Flashcard

Front

What are neurons?

Back

Neurons are specialized cells of the nervous system that transmit information through electrical and chemical signals.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) provides energy for various cellular processes by releasing energy when its chemical bonds are broken.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can create its own food using sunlight or chemical energy, typically through photosynthesis.

Front

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.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs obtain food by consuming other organisms (e.g., animals, fungi).

Front

What is the significance of breaking the bond between the second and third phosphate groups in ATP?

Back

Breaking the bond between the second and third phosphate groups in ATP releases energy that can be used for cellular work.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is the chemical equation for photosynthesis?

Back

The chemical equation for photosynthesis is 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What is the function of sodium and potassium ions in neurons?

Back

Sodium and potassium ions are essential for generating and transmitting electrical signals in neurons.

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.
