Runners rely on muscles to propel them as they run. Muscles require a continuous supply of oxygen and glucose for contraction. Metabolism of these reactants generates carbon dioxide and lactate. Consider as the system the thigh muscle of a person during a 1000-m race. You wish to model glucose during the race.

Explanation:

The Cori cycle is the cyclic circulation of glucose and lactate between muscle and liver.

Muscle cells feed primarily on glucose from their glycogenic stores and especially from what comes through the bloodstream from the liver. During muscular work, in the presence of great anaerobic glycogenolytic activity, large amounts of lactate are produced, which diffuses into the blood to be taken to the liver. This is because muscle cells lack the enzyme glucose-6-phosphatase, so phosphorylated glucose cannot go into circulation. Lactate in the liver is converted back to glucose by gluconeogenesis, returning to the circulation to be taken back to the muscle. It represents the integration between glycolysis and gluconeogenesis of different body tissues.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
