What did everyone put for why insulin is still secreted? I put because it takea a while before all the calcium ions leave the cell via active transport so whilst they're atill in the cell theyll still cause exocytosis even if no more glucose is being taken in

I don't know the answer, but I put because blood glucose conc hasn't come down to optimum yet, and so negative feedback hasn't happened yet.

For that I wrote that not all of the calcium ions would have been removed
