🌎Disaccharide formation: 1) Maltose🍁 α-glucose + α-glucose --> Maltose 2) Lactose🍁 Glucose + Galactose --> Lactose 3) Sucrose🍁 Glucose + Fructose --> Sucrose 🌀Tips: The type of equation disaccharide above : glucose + (glucose/galactose/fructose) so yall can try to memorize - gaLACTOSE (mono) for LACTOSE (di), - Fructose (mono) for Sucrose - Maltose(di) is the easiest because glucose + glucose

Explanation based on this video: https://t.me/Matrikulasi2021/1579 1) Ca²+ --> Synaptic knob. • Ca²+ ion influx into the synaptic knob. 2) synaptic vesicles -> ruptures • The influx of Ca²+ ion causes the synaptic vesicles to fuse with the presynaptic membrane & rupture. 3) neurotransmitter -> synaptic cleft • Raptured synaptic vesicles releasing neurotransmitters into the synaptic cleft by exocytosis. 4) neurotransmitter -> receptor site • The neurotransmitter substance diffuses across the synaptic cleft and is attached to a specific receptor site on the postsynaptic membrane. 5) ligand-gated ion channel opened • Causing the opening of the ligand-gated ion channel at the postsynaptic membrane. 6) Na+ --> postsynaptic knob • Na+ ions influx the postsynaptic knob down their respective concentration gradient. --------- [psst: this video is just a part of the process means not a full process explanation. So before the Ca²+ influx to the synaptic knob, & after the Na+ influx into the postsynaptic knob there are some explanations left behind ya, for that part u study yourself 😄]
