Concept explainers
(1)
To explain: With regard to spinocerebellar pathway, the type of sensory receptor involved and the type of sensory information provided to the brain.
Concept introduction: The nerve signals are relayed from the brain to other organs through the spinal cord. Based on the direction of nerve signals, synapse conduction pathways are of two types: sensory pathways or motor pathways. Sensory pathways are also known as ascending pathways and relay sensory input to the brain. There are three somatosensory pathways: posterior funiculus-medial lemniscal pathway, anterolateral pathway, and spinocerebellar pathway.
(2)
To explain: With regard to spinocerebellar pathway, location of each of the sensory neurons within the chain of two neurons that compose this pathway.

Write out a 5-step general acid/general base mechanism to explain how HMG-CoA isformed from 3 acetyl-CoA (Note: we are leaving out some details. The enzyme HMG-CoA actuallyuses its Cys residues to accept acetyl groups from 2 acetyl-CoA, making new thioesters and liberatingCoASH) B. Two NADPH and two H+ are required to form mevalonic acid from HMG-CoA. Circle the Hatoms that came from NADPH, and put a square around any H atoms that came from H+.C.
