Enzymes are used to speed up reactions. They’re also called catalysts and their main purpose is as a speed boost for reactions
The layers and structures the needle passed through are- epidermis, dermis, subcutaneous layer or hypodermis, connective tissue layer and muscle.
The epidermis is the outermost layer of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The connective tissues connects, binds and separates other tissues or organs. Muscles are soft tissues found in the body. They function to produce force and motion.
