Explain the lock and key example
Definition
wwweeelllllll, the enzyme is the key and the substrate is the lock and the lock can only be used once but the key can be used infinately which doesnt really make any sense to me so i usually just use the lactose exampleeee. FOR EXAMPLE, your body is already fully equipped with enzymes called lactase(you can tell its an enzyme because of the ase suffix) and the lactase is made to break down a  substrate called lactose(which is a disaccharide sugar for energy) so the lactose breaks down and goes away while the lactase stays and breaks down more of the same lactoses, so the key thing is more like lactose in general is a lock  so lactase cannot break down(or fit) into anything but lactose. MY body, however, doesnt have enough lactase enzymes, so my body cannot break down the lactose fast enough which is known as Lactose intollerance, which i CAN regain some lactase enzymes with time.

what was Redi's experiment and what did it prove?
Definition

In one experiment, Redi took six jars, which he divided in two groups of three: in the first jar of each group, he put an unknown object; in the second, a dead fish; in the last, a raw chunk of veal. Redi took the first group of three, and covered the tops with fine gauze so that only air could get into it. He left the other group of jars open. After several days, he saw maggots appear on the objects in the open jars, on which flies had been able to land, but not in the gauze-covered jars.

He continued his experiments by capturing the maggots and waiting for them to metamorphose, which they did, becoming flies. Also, when dead flies or maggots were put in sealed jars with dead animals or veal, no maggots appeared, but when the same thing was done with living flies, maggots did.

 

this proves that fly larvae only comes from adult flies.
