They can. In cellular respiration proteins may be broken down and modified to enter as part of the citric acid (Krebs) cycle.
Smaller molecules called amino acids make protein molecules.
Amino acids.
Lipids are molecules that can be used for both energy storage and as structural material. They are stored in cells as fat for long-term energy needs, and also make up cell membranes as a structural component.
Actin and myosin are proteins. Protein is a broad category of molecules.
Protein
Actualy glycogen is not a protein but it is a polymer of glucose molecules stored in animal bodies and used as energy source when needed.
When a photosystem protein is hit by a photon of light, it excites an electron within the pigment molecules in the protein. This electron is then passed along a series of molecules in the photosystem, creating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH.
mitochondria doesnt make protein it makes energy
by breaking chemical bonds in the molecules
By breaking chemical bonds in the molecules
Protein can provide energy, but this is extremely inefficient. This is due to the fact that the energy it takes to make it usable as energy is almost as much as the energy it provides.
AnswerIt can be a peptide, if it is of medium size, and the biggest is a protein molecule. A large molecule made up of amino acids may also be an enzyme.
