troponin<\/a>, which changes the shape of tropomyosin, exposing the active sites on actin, which can now attach to myosin heads. Myosin heads use the energy from ATP to power a cross-bridge cycle. In the cross-bridge cycle, myosin heads bind to actin and then use the energy from ATP to power a conformational change. <\/p>\n\n\n\nThis change causes the myosin head to pivot, which pulls the actin filament towards the center of the sarcomere. The pivoting action of myosin heads is what produces muscle contractions. Muscle contractions are necessary for many functions, including movement, posture, and heart function.<\/p>\n\n\n\n
Active Transport: <\/h3>\n\n\n\n
Active transport is the movement of molecules across a membrane against a concentration gradient. Active transport requires ATP. Molecular pumps use the energy from ATP to pump molecules across a membrane. The most common type of molecular pump is the sodium-potassium pump. The sodium-potassium pump uses ATP to pump sodium ions out of cells and potassium ions into cells, creating a concentration gradient of sodium and potassium ions across the cell membrane. The sodium-potassium pump is responsible for maintaining the resting potential of neurons. <\/p>\n\n\n\n
Synthesis of Macromolecules: <\/h3>\n\n\n\n
Synthesis of macromolecules is the process of synthesizing large molecules from smaller molecules. Synthesis of macromolecules requires ATP. ATP is essential for many cellular processes, including active transport, muscle contraction, and the synthesis of macromolecules. Enzymes require ATP to catalyze reactions. DNA polymerase uses ATP to add nucleotides to DNA strands during replication. RNA polymerase uses ATP to add nucleotides to RNA strands during transcription. Ribosomes use ATP to synthesize proteins during translation. Synthesis of macromolecules is necessary for many cellular processes, including DNA replication, transcription, and translation.<\/p>\n","protected":false},"excerpt":{"rendered":"
Aerobic Cellular Respiration Aerobic and anaerobic respiration are two types of cellular respiration. Aerobic cellular respiration requires oxygen, while anaerobic respiration does not. Aerobic respiration is more efficient than anaerobic respiration and produces more ATP. However, anaerobic respiration is faster and used when oxygen is unavailable. Aerobic cellular respiration occurs in the presence of oxygen […]<\/p>\n","protected":false},"author":6,"featured_media":9996,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[27,25,33],"_links":{"self":[{"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/posts\/9995"}],"collection":[{"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/comments?post=9995"}],"version-history":[{"count":4,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/posts\/9995\/revisions"}],"predecessor-version":[{"id":10006,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/posts\/9995\/revisions\/10006"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/media\/9996"}],"wp:attachment":[{"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/media?parent=9995"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/categories?post=9995"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/iaf.care\/wp-json\/wp\/v2\/tags?post=9995"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
