WebQuestion. Describe the genetic code and its relationship to polypeptides and proteins. [5] a. Outline the role of proteins in active and passive transport of molecules through membranes. [5] b. Many cell functions, like synthesis of macromolecules and transport, require energy in the form of ATP. Explain how ATP is generated in animal cells. WebAerobic Respiration (with oxygen again) Within two minutes of exercise, the body starts to supply working muscles with oxygen. When oxygen is present, aerobic respiration can take place to break down the glucose for ATP. This glucose can come from several places: remaining glucose supply in the muscle cells. glucose from food in the intestine.
What do ATP and ADP mean? What are the roles of these …
Web4 de fev. de 2024 · The synthesis of ATP in chloroplasts, promoted by light, is called photophosphorylation. It is driven by the proton motive force generated during the flow of electrons from the light stage. The protons flow through the ATP synthase enzyme complex, which crosses the lipid matrix of membranes. WebATP Production.
