Dehydration reactions.
photosynthesis
Yes, foods eaten by animals are composed of macromolecules such as proteins, carbohydrates, and lipids, which provide essential nutrients for growth and energy. These macromolecules are broken down during digestion into smaller molecules that can be absorbed and utilized by the animal's body for various biological processes.
The general term for very large molecules is "macromolecules". There are special terms for different specific types of macromolecules, like "polymers" or "proteins", and most people studying them specialize in one or another specific type.
receptor-mediated endocytosis
No, but most macromolecules are organic molecules (with a backbone made of carbon atoms). But it is possible to synthetically create macromolecules with a backbone made of silicon atoms (i.e. the silicones), boron atoms (i.e. the boranes), and a few others. The atoms attached to the backbone or forming side branches extending away from the backbone can be any element on the periodic table.

Metabolism is the biological process that provides most of an organism's thermal energy. As organisms break down nutrients through metabolic processes like cellular respiration, heat is released as a byproduct, which helps regulate body temperature.
Proteins are constructed from amino acids through a process called protein synthesis. During protein synthesis, amino acids are linked together in a specific sequence dictated by the genetic code encoded in DNA. This process involves transcription of DNA into messenger RNA, and then translation of mRNA into a sequence of amino acids, which ultimately folds into a functional protein.
Most macromolecules are made up of thousands of smaller molecules called monomers. These monomers are linked together through chemical reactions to form polymers, which are the large macromolecules found in living organisms.
Scientists think that protobionts formed by accidental natural causes.
Molecules of carbons are known as orgains. Since carbon is the main atom of carbohydrates, proteins and other macromolecules they are said to be organic. There is no in organic macromolecules exist in our cell.
