Which of the following groups of proteins would probably have a signal sequence? Enzymes found in lysosomes Glycolytic enzymes in bacteria Hormones synthesized in endocrine cells 2 Both 1 and 3 are correct 3 1

Solution

Both 1 and 3 are correct.

Lysosomal enzymes are targeted from their location of synthesis in the rough endoplasmic reticulum to the lysosomes with the help of a group of protein and carbohydrate recognition signals present on the enzymes.

Glycolytic enzymes do not have recognizable export signal sequence.

Endocrine signaling involves movement of hormones through the circulatory system to function on the distant target cells.
