To identify the step of the citric acid cycle in that ATP-precursor-molecule generated is equivalent to 2.5 units of ATP. Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and CoA-SH . NADH is the reduced form of nicotinamide adenine dinucleotide. It is employed as an oxidizing agent in various reactions like oxidation of secondary alcohol into a ketone . Its structure consists of three subunits: nicotinamide, ribose, and ADP.

A few hours after the death of an animal, the corpse will stiffen as a result of continued contraction of muscle tissue (this state is called rigor mortis). This phenomenon is the result of the loss of ATP production in muscle tissue.(a) Consult as shown and describe, in terms of the six-step model of muscle contraction, how a lack of ATP in sarcomeres would result in rigor mortis.(b) The Ca2+ transporter in sarcomeres that keeps the [Ca2+]∼10-7 Mrequires ATP to drive transport of Ca2+ ions across the membrane of thesarcoplasmic reticulum. How would a loss of this Ca2+ transport functionresult in the initiation of rigor mortis?(c) Rigor mortis is maximal at ∼12 hrs after death and by 72 hrs is nolonger observed. Propose an explanation for the disappearance of rigormortis after 12 hrs.
