In a study, researchers put human participants on a treadmill for 10 minutes and then drew blood samples. They found that blood
levels of certain "exercise metabolites" increased after the participants exercised. When the researchers added these "exercise metabolites" to mouse muscle cells cultured in a lab dish, the cells increased the rate at which they were burning _______
Metabolism Are processes, usually chemical processes , which are required or needed in the body to sustain or maintain life.
Metabolism can be breaking down of complex molecules to obtain energy, known as catabolism, or building up of complex molecules through energy use.
Metabolites are involved in and essential in metabolism. At times they might be products of metabolism. Examples are fructose and glucose .
In this case, the exercised metabolites that were found in the human were products of metabolism and they give energy. They were able to increase the rate at which fats are burning in the mouse because they acts on fats to supply or give energy to the body.
Compare and contrast a frameshift mutation and a single nucleotide substitution mutation in a DNA sequence encoding a protein. How many nucleotides would be inserted or deleted in each? How many amino acids in the protein sequence would be altered in each?
