A fixed amount of radiolabelled insulin was incubated with a fixed amount of anti-insulin antibody, the bound ligand was separated from free ligand at different time intervals. Draw a diagram of the concentration of the insulin/antibody complex with time. (Insulin/antibody complex is the bound ligand) asap typed only .

Which statement best describes the principle behind the succinate dehydrogenase (SDH) assay used in the assay of subcellular fractions from mung bean seedlings?     Question 11 options:   SDH oxidized succinate to fumarate, then fumarate reduced DCPIP.   Succinate is blue in colour, which is eliminated by its oxidation to fumarate by SDH.   SDH produced FADH2, then FADH2 reduced DCPIP.   SDH generated DCPIP, then DCPIP oxidized succinate to fumarate.
