Growth factors are cell-surface receptor-binding proteins that encourage the growth and development of target cells.
<h3>What is Growth Factor ?</h3>
A growth factor is a naturally occurring chemical that promotes cell proliferation, wound healing, and, on rare occasions, cellular differentiation. It is usually a secreted protein or a steroid hormone. Growth factors play a crucial role in the regulation of many cellular processes.
- A growth factor is a protein that stimulates the growth of specific tissues. Growth factors are found in a wide variety of animals, including insects, amphibians, humans, and plants, and they serve a crucial role in encouraging cellular differentiation and cell division.
- Growth factors are commonly used as a signaling molecule between cells. Cytokines and hormones, for example, attach to specific receptors on the surface of their target cells. As a result, the correct answer is proteins that bind to surface receptors and excite target cells.
Growth factors are local regulators that - bind to cell-surface receptors and stimulate growth and development of target cells.

Answer:
The inner membrane of a mitochondria are made up of phosphoslipid bilayer just like all membranes surrounding animal cells. The bilayer is made up of hydrophobic tails which point inwards, and the hydrophilic layer pointing outwards away from the inner fluid layer. Thus entry of substances into and out of the cells cytoplasm are well regulated.
Layers of protein are embedded in the membrane to transport electron spitted from Hydrogen atoms deposited by FADH2 and NADH2 into the matrix. This set up gradient for the transport of electrons in chains called Electron Transport Chain.
The adaptive features of of inner membrane is its large surfaces areas to volume ratio to accommodate enough hydrogen ions / protons pumped by PMF, needed to set up electrochemical gradient for energy used by ATPase Synthase for ATPs production.
Enzymes are proteins. therefore the smaller units are amino Acids units are linked by polypeptides chains. Basically carboxyl group,Amino group, Hydrogen and R-group( which determines the nature of Amino Acids) are the basic functional group of Amino Acids.
Enzymes are globular proteins formed from confrontational change on the amino acids moiety ,
They are organic catalyst which speed up the rates of biochemical reactions in living organism.
