Question
alof following is incorrect regarding muscle (li) of the shich4. Hiftion? mosin make actomyosin. Hin and myosin make dctrom phosphocreatine.(a)energy.
Step 1
The first statement says that actin and myosin make actomyosin. This is true as actin and myosin are proteins that interact with each other during muscle contraction to form a complex called actomyosin. Show more…

filaments striated muscle myosin, filaments and energy from ATP of the steps Thick filaments; thin primarily actin, lower muscle are the muscle cell movement myosin filament contraction?
Which statement on muscles is incorrect? Select one: a. Actins are fibrous proteins that form microfilaments. b. An individual sarcomere unit consists of overlapping actin and myosin. c. Myosin contributes to muscle contraction and is ATP dependent. d. Actin filaments are made up of identical actin proteins arranged in a spiral-like chain. e. Myosins are motor proteins that interact with actin.
Energy for Muscle Contraction Initially, muscles use stored ATP for energy. Bonds of ATP are broken to release energy. Only 4-6 seconds worth of ATP is stored by muscles. After this initial time, other pathways must be utilized to produce ATP: 1. Direct phosphorylation 2. Aerobic respiration 3. Anaerobic glycolysis (a) Direct phosphorylation of ADP by reaction with creatine phosphate (CP) Energy source: CP Only muscle cells contain creatine phosphate (CP) CP is a high-energy molecule After ATP is depleted, ADP is left Oxygen Usage: None Products: ATP, CP, creatine Duration of energy provision: 15 seconds CP transfers energy to ADP to regenerate ATP. CP supplies are exhausted in about 20 seconds.
