<span>Enzymes are used up as a part of the reaction and cannot be used again. Enzymes can be any shape to bind to the substrate. Enzymes are catalysts that lower the activation energy allowing the reaction to occur. Enzymes are formed into lipids. 3. Which macromolecule is most likely to be broken down for quick energy? nucleic acid carbohydrate phospholipid protein
The Central Role of Enzymes as Biological Catalysts. A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.</span>
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.
Answer: B-cells fight bacteria and viruses by making y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells. C-cells are a virus-bound antibody that binds to receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis, by which the cell engulfs and destroys the virus.
Explanation: sorry this answer was not simple at all -_-
