Metabolismo

The video explains how cells extract and convert energy from food to fuel various cellular processes. It highlights that many metabolic pathways are conserved across different species, indicating a fundamental similarity in biological processes.

What is the primary purpose of extracting energy from food in cells?

• To eliminate waste

• To convert it into fat

• To store it for future use

• To use it in cellular processes

How do cells utilize the energy extracted from food?

• By converting it into water

• By storing it in the nucleus

• By using it in various cellular processes

• By releasing it as heat

Which of the following best describes the consistency of metabolic pathways across species?

• They are identical in all species

• They are unique to each species

• They vary significantly between species

• They are mostly similar across different species

What is a common feature of metabolic pathways in different species?

• They are mostly similar

• They are similar only in plants

• They are completely different

• They are only similar in mammals

Why is it significant that metabolic pathways are similar across species?

• It indicates identical energy needs

• It allows for the same diet in all species

• It suggests a common evolutionary origin

• It means all species have the same lifespan
