What is likely to happen to a protein molecule that is exposed to intense heat or radiation?

A protein may become denatured when exposed to intense heat or radiation. When a protein becomes denatured, its basic structure is damaged enough that it is no longer able to function.

How radiation is harmful to us?
Radiation is never beneficial to a healthy human. Radiation in human means energy carried by a wave (electromagnetic waves) or a particle (proton, neutron, etc.) penetrates the human outer skin layer and gets absorbed by the cells, blood or water. The result is a nuclear reaction -- molecule bonds get broken or tissues get hot, for example. If that molecule is involved in cell division or protein replication, the long-term effect can lead to cancers. If the cell damage or heat generation is too intense for the body to repair itself fast enough, the organ ceases to function (imminent death). Chemotherapy is considered a very mild form of radiation, compared to exposure to cosmic rays or nuclear weapons, but Chemotherapy already has severe side effects, like losing hair and loss of appetite. X-rays in a hospital are milder still and exposure is temporary. Long-term exposure to the sun, without a constant application of SKF30 or better sunblock lotion or wearing a hat or polarizing sunglasses, will have a larger impact than infrequent X-rays -- skin cancers. Even without exposing to the sun, we are still exposed to background radiation from the air and soil (residual radioactive isotopes, such as radon). We cannot escape from radiation, but we can mitigate greatly to reduce the accumulated dose and radiation effects. Please see the related link. ===========================
How does a large particle leave a cell by a active transport?
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
Why is X-ray radiation required in protein structure determination?
Protein structure determination is basically crystallography i.e. finding out the arrangements of atoms. This technique uses Diffraction maxima and minima to determine 3D structures. For diffraction to occur, the size of the obstacle must be close to the wavelength of light used. Since the obstacles in this case are molecules, we use X rays, whose wavelength is comparable to radius of molecules.
Why is Serratia marcescens more susceptible to ultraviolet radiation than Bacillus cereus?
UV radiation exposure to S. marcescens colonies results in DNA mutations. The radiation energy is absorbed by the bacteria and if exposure is long enough, thymine nitrogenous bases adjacent to each other in DNA strands will form cyclobutane rings called thymine dimers. When replicating DNA and multiplying, the enzymes responsible for replication will bond a different base in place of the thymine bases and a mutation will result. How if affects the DNA, and consequently protein synthesis, is entirely dependent on the location of mutations.
How much protein should I take, based on my weight?
A normal individual’s Protein requirement varies in different stages of his/her life. Kids, adolescents, adults, and senior citizens require a different amount of protein every day. To calculate this, you can use GRD - The Superior Protein’s BMI protein Calculator. The calculator will help you assess the amount of Protein you need as per your body weight. If you’re wondering which Protein brand to buy, then you should consider going for GRD - The Superior Protein. GRD Superior protein has a high-quality category of whey protein that comes from milk and is one of the highest whey protein brands. It makes delicious Protein Biscuits for kids known as GRD Bix. These biscuits are perfect to snack on the go and come in 6 delicious flavours. For diabetic patients, GRD - The Superior Protein has the GRD - SugarFree biscuits which comes with no added sugar and is the best protein powder for diabetics. Whereas for people who are into fitness and building their health, there is GRD Lite and GRD - The Superior Protein, which are two options for a perfect protein dose every day. Protein is one of the most important building blocks of the body, helping in recovering muscle tear as well as helping the body to function properly. One should never compromise on their protein source and that’s why GRD - The Superior Protein is one of the top protein brands in India out there. You can buy all the aforementioned products online from their website

A characteristic of a DNA molecule that is not a characteristic of a protein molecule is that the DNA molecule?
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
What is the molecule called that can bind to a receptor protein?
The molecule that can bind to a receptor protein is called a ligand.
What molecule is larger protein or salt?
Depends greatly on the salt or the protein. There is not one salt or one protein molecule, so you will have to be more specific.

What occurs to a molecule of the enzyme trypsin AFTER human pancreas binds to a molecule of protein?
Trypsin is an enzyme that is produced in the pancreas. After the human pancreas binds to a molecule of protein, auto catalysis occurs to a molecule of trypsin.
What molecule is formed from polypeptides?
protein
