In which of the following scenarios would energy be mostly derived from anaerobic metabolism? a. when an athlete is in a steady state or at restb. when an athlete begins an activityc. when an athlete experiences temporary fatigued. when an athlete reduces the duration of an activity

Option C

Explanation:

The situation of fatigue occurs in an athlete when he/she is doing rigorous exercise or an activity requiring intense muscular activity. In these scenarios, muscles cells undergo anaerobic respiration which eventually leads to acidification and hence fatigue in muscles. Also during this scenario, the resting membrane potential of the muscles depolarizes and muscle may deplete in severe cases. Thus, during temporary fatigue muscle experiences highest level of anaerobic respiration.

Option C is correct

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
