Questions and Answers

What are the two fundamental conditions for life?

The organism must be able to self-replicate and it must have a nucleus
The organism must have a cell membrane and be able to produce energy from the environment
The organism must be able to produce energy from the environment and it must have a nucleus
The organism must be able to catalyze chemical reactions efficiently and selectively, and it must be able to produce energy from the environment (correct)

What is the role of enzymes in biochemical processes?

To coordinate metabolic pathways and sustain life (correct)
To self-replicate and catalyze chemical reactions
To produce energy from the environment
To transport nutrients to different parts of the organism

Why is catalysis important for sustaining life?

Catalysis is necessary for self-replication
Catalysis helps transport nutrients to different parts of the organism
Chemical reactions such as sucrose oxidation could not occur on a useful time scale without catalysis (correct)
Catalysis is necessary for the organism to produce energy from the environment
