Question

part 1: enzymes

1. what is an enzyme?
2. why is it important that living things have enzymes?
3. list some traits of enzymes.

Explanation:

1. An enzyme is a biological catalyst, usually a protein, that speeds up chemical reactions in living organisms by lowering the activation - energy required for the reaction.
2. Enzymes are crucial for living things as they facilitate metabolic processes such as digestion, energy production, and DNA replication. Without enzymes, these reactions would occur too slowly to sustain life.
3. Traits of enzymes include specificity (they act on specific substrates), catalytic efficiency (they greatly increase reaction rates), and regulation (their activity can be controlled by factors like temperature, pH, and inhibitors/activators).

Answer:

1. An enzyme is a biological catalyst, often a protein, that accelerates chemical reactions in living organisms by reducing the activation - energy.
2. Enzymes are important for living things as they enable metabolic processes like digestion, energy production, and DNA replication which are essential for life.
3. Specificity, catalytic efficiency, and regulation are some traits of enzymes.
