Answer:
(B) Energy released from the chemical reaction is used to directly phosphorylate ADP.
(D) Energy released from the chemical reaction is used to directly reduce NAD+
Explanation:
phosphorylation is a addition of phosphoryl group to an organic compound.Substrate level phosphorylation is a process where there is ATP is produced from ADP by transferring a high energy phosphate group from phosphorylated metabolic compound.This process occurs in glycolysis and citric acid cycle.and this pathway is exergonic pathway
Answer:
C. there are twelve frogs, which is the most
Striated muscles contain repeating sarcomeres of overlapping arrays of long, thin actin and thicker myosin filaments. Myosin filaments contains the myosin heads, which are enzymes that can bind to actin, split and make use of the energy from ATP. When muscle contraction starts, myosin heads bind to actin, change their configuration on actin, liberating the products of ATP hydrolysis and causing slide of the actin and myosin filaments. The action of the proteins troponin and tropomyosin on the actin filaments regulates vertebrae striated muscle contraction. The release of calcium ions from the sarcoplasmic reticulum is triggered by the nervous stimulation which causes depolarization of muscle membrane. Calcium ions bind to troponin and thus cause or allow the tropomyosin strands on the actin filament to move so that the part of the actin surface where myosin heads need to bind is uncovered. Contraction then occurs and only stops when the sarcoplasmic reticulum pumps calcium out of the muscle interior.
So basically, what triggers the uncovering of the myosin binding site on actin is the calcium ions binding to troponin and changing configuration.
