Question

pletion Status Nemo Give the name of the general organelle found in most cells that corresponds to the specialized version in muscle fibers (These blank may need more than one word). sarcolemma sarcoplasm sarcoplasmic reticulum myofibril mitochondrion QUESTION 2 is covered by which is The structure of a muscle as an organ is defined by its layers of connective tissue. The entire the mysium, and the mysium covers each composed of individual each surrounded by mysium 6 points QUESTION 3 Explain the chemical basis of why contraction of skeletal muscles produces body heat? TT T Arial 3 (1200) TEE

Answer 1

Cell. coveas 0 Answers :- © Sarcolemma plasma membrane Sarcoplasm cytoplasm dascoplasmic reticulum – endoplasmic peliculum myofibril Mitochondrion mitochondria. Sarcolema a specialized cell membrane Surrounding muscle fiber cells and is similars to plasma membrane and sarcoplosm is similars to cytoplasm etc. © The stoucfuse of a muscle as an organ is defined by its layers of connective tissue. The entire muscle is covered by the lepimysium , and the perimysiwa each ifas cicle) which is composed of individual muscle fiber each surrounded by Tendo mysium]. 3 The main feature of skelefal muscle is that it is able to transform Chemical eneogy from nutrient molecules into mechanical energy which makes' muscle force. Muscles have the ability to generale heat they contract, the energy needed to produce muscle contraction is obtained from Adenosime teriphosphate whes muscle uses ATP as power source an exothermic reachiom occords which bréages up. ATP, molecules into App molecule and phosphates els the liberalion of heafeneage this liberoled heap'energy is used up by the muscles to produce 'muscle contaction (shortening of muscle fibre), but the muscle are unable to ufilise 100% of this energy, the remaining part of energy Liberefed in the form of heat, moreovers when the muscle fibres tighten and flex, they rub each other causing friction, which can Liberafe small amount of heat, when we exercise more amount of ATP is used up, which means more heaf is been released by the ATP hydrolyses reactio. capable of exerting is

please give thumps up if answer is satisfactory...thank you!!
