Would it be justified to call Kreb's Cycle the central wheel of metabolism? Why? Provide two specific pieces of evidence to support your answer.

Yes.

Explanation:

Kreb's Cycle is considered as the central wheel of metabolism because the fuel molecules are oxidized ultimately within the Krebs Cycle and its intermediates are used for various biosynthetic pathways. The main function of the Kreb's cycle is to produce electron carriers that can be used in the cellular respiration for producing energy molecules in the form of ATP. without Krebs's cycle, the cell produces only two ATP molecules which very low.
