Living things need energy. Why? To grow, heal, move and more. For plants, animals and fungi, the energy comes from cellular respiration. That’s why cellular respiration is one of the most important biochemical processes for life on Earth. Wondering what a biochemical process is? Biochemistry combines chemistry and biology. It is the study of the chemical reactions that occur in living organisms. Cellular respiration is really a set of chemical reactions. There are several steps in the process, but eventually, energy from nutrients is converted into high-energy molecules, and waste is released. This process illustrates one characteristic of living things: they take in nutrients and release waste.

Question

Based on the passage, which of the following might a biochemist study?

A
the reactions that occur when acid rain hits a brick building

B
the reactions that occur when a person digests a burger

C
the interactions between different animals in the rainforest

D
the different ways animals respond to being surprised

Answer 1

Based on the passage, a biochemist would study the chemical reactions that occur in living organisms. Therefore, the correct choice is:

B) the reactions that occur when a person digests a burger.

This option relates to the biochemical processes involved in digestion, which includes the chemical reactions that break down nutrients, similar to those involved in cellular respiration. The other options do not focus on biochemical processes in living organisms.
