Unit 3 Energy Flow Test #1

Front

What type of reactions usually feel cold?

Back

Endothermic reactions absorb heat from their surroundings, resulting in a cooling effect.

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate.

Front

What is the primary function of ATP in living organisms?

Back

ATP (adenosine triphosphate) provides energy for cellular processes.

Front

What organelle is responsible for protein synthesis and transport?

Back

Endoplasmic reticulum.

Front

Which organic compound is the main source of energy for living things?

Back

Carbohydrates are the primary source of energy for living organisms.

Front

What are exothermic reactions?

Back

Exothermic reactions release heat, causing the temperature of the surroundings to increase.

Front

Define mitochondria.

Back

Mitochondria are organelles known as the powerhouses of the cell, where energy production occurs.

Front

What role do enzymes play in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the difference between substrates and products in a chemical reaction?

Back

Substrates are the starting materials in a reaction, while products are the substances formed as a result of the reaction.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.
