Question 6

Where do macromolecules come from?

Answer 6

Diet, biosynthesis from scratch, symbiosis in gut, metabolism

Question 7

Biochemical themes

Answer 7

Reversible chemical bonds store energy
Energy needed for homeostasis
Need to capture and store chemical energy and information
Monomer/polymer/aggeregates
Simple compounds interact to make big interactions and functions
