The palm has thicker skin and it is tougher because the inside of your hand needs more protection from touching more things
The two choices that support my answer are
B The Mitocondria in the muscles generate through cellular respiration.
E The lungs support cellular respiration by providing need to produce ATP from the carbohydrates
Explanation:
Eating lots or carbohydrate or carb loading leads to increase the rate of aerobic respiration in various cells such as liver,muscle that generate energy in form of ATP and the excess energy is being stored. This excess stored energy helps to maintain healthy body physiology among marathon runners .
During the Catabolism of carbohydrates in aerobic condition oxygen is very much essential.Oxygen is brought into cell by the normal physiologic functioning of lungs.In presence of oxygen carbohydrates are broken down by various metabolic pathways such as glycolysis to generate ATP .
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
