glucose levels go up in the bloodstream after a meal. beta cells of the pancreas detect the elevated glucose levels. this causes
Keith_Richards [23]

The secretion of insulin into the bloodstream is done through exocytosis and absorption through the capillary arteries.

Insulin is a protein required to process sugar. This is a <u>naturally produced protein</u> for which the pancreas is responsible. The insulin Protein is considered a transport protein. It is responsible for carrying glucose from the bloodstream into cells to be used as energy.

This protein is of vital importance. The secretion of this protein is done through exocytosis, which means that after passing through the ribosomes and the Golgi, it is contained within a membrane, which will then fuse into the plasmatic membrane and be released from the cell. It is then absorbed through the capillaries to enter the bloodstream.

A box of jello has a mass of 250 g. How many boxes must be bought to have 1 Kg of jello? *
Igoryamba

Answer:

4

Explanation:

According to the question, one box of jello has a mass of 250grams.

The question wants us to find how many boxes of jello would collectively weigh 1kg.

Since the units of weight here are in grams (g) and kilograms (kg), we need to convert to the same unit

1kilogram (kg) is equal to 100 grams (g).

Hence, if 1 box of jello weighs 250g

1000g of jello box will be 1000/250 in number

1000 ÷ 250 = 4.

Hence, 4 boxes of jello will weigh 1000g or 1kg.
