Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
leva [86]

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

The cell cycle has three important phases Interphase, M -phase and cytokinesis. Interphase is the laongest phase of eukaryotic cell cycle. This phase shows no observational change in the cell, however, it collects nutrients, generates protein and replicates DNA and prepare the cell for the M- phase.

Interphase has 3 phases G1, S, and G2 phase. G1 phase is the phase that collects nutrients and increase the size of the cell for the cell division. S phase or synthesis phase is the phase takes maximum time in cell divivon and acompanied by protein generation, duplication of the genetic material. G2 phase is preparatory phase that prepeare the cell before the cell enter in the M - phase.
