Arunner is running the 60-meter dash, which is an oxygen-deficient race. what type of energy is the runner's body using to power through the race? a. catabolic b. aerobic c. anaerobic d. anabolic

C

Explanation:

This type of cellular respiration occurs in the cytoplasm of the cell rather than the mitochondria. It is mainly powered by the glycolysis metabolic pathway that produces pyruvate as an end product of breaking down glucose. The pyruvate, if oxygen is availed to the cells, is converted to acetyl-CoA and enters the Kreb cycle in the mitochondria. However, if oxygen is unavailable (like in this case), the pyruvate is converted to lactic acid. Lactic acid if accumulated in the muscle causes muscle pulls hence needs to be broken down fast by cells and excreted.

the cytokine-activated janus kinase (jak)-signal transducer and activator of transcription (stat) pathway has an important role in the control of immune responses. dysregulation of jak-stat signaling is associated with various immune disorders.
