Which of these does not increase during heavy exercise? oxygen extraction from the blood by muscles body heat production minute ventilation oxygen delivery to muscles arterial pco2 ©2017 mcgraw-hill education. all rights reserved?

Arterial PCO₂ do not increase during heavy exercise. PCO₂ or the partial pressure of carbon dioxide is the measure of the relative concentration of the gas in a fluid. PCO₂ do not change during exercise . PCO₂ will only increase for systemic venous blood pressure, not the arterial blood pressure. Alveolar ventilation increases with the same amount as carbon dioxide that is why alveolar and arterial PCO₂ do not change. Oxygen extraction from the blood by muscles increases because the blood will flow rapidly inside the system. The muscles will take in more oxygen from the blood because of the activity. And because of the intense activity, the body will produce more heat.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
