1. Enzymes have an area inside them called an active site, this is the "hole of the engyme" or the "lock". There, a substrate will fit into the active site like a key into a lock, resulting in a product.

Enzyme have an area inside called the active site. This active site is has a whole in it and that is were the substrate fits into it ending up with a product. Enzymes are proteins. Blood contains a molecule called heme which is an example of a cofactor. Heme are located in the middle of the blood cell and it creates protein. Competitive inhibition are the ones who "compete" blocking the site while allosteric inhibition change the shape. Cofactors and coenzyme are the two different factors that could affect the enzyme rate.

1)The enzyme has an opening or hole ,that is call active side (lock), where it enters the substrate (key), that would cause them breaking apart to deliver products.

1) In an enzyme, the active site is the lock and the substrate is the key, allowing for the products to be produced as a result.

An example of an enzyme is catalase. An enzyme consists of a substrate and an active site. The active site is in the inside of the enzyme and the substrate is inside the active site. When the substrate breaks off the active site we have a product. Enzymes speed up chemical reactions and are the macromolecule protein.

1. In the catalase/enzyme there is a specific shape known as an active site which can be pictured as an outline (hole) for a key, the key would be known as the substrate, and then ending up with products or results.

1) the enzyme has a hole (keyhole) or in other words active site where the subtrate is inserted and formed into a product of 2H2O2+O2

Enzymes Washington right as a lock. They have a hole called the active site which attracts the substrate( the key. The enzyme thugs the substrate and breaks it apart in seconds because some substances can be very harmful for our body. Something very cool about enzymes is that they only mix with an specific substance and does not confuse even with other similar substances.

1. Enzymes have an area inside them called an active site, which has a hole in it somewhat like a lock. The substrate is what goes inside the lock, like a key, and is broken down into products. The key and lock are a perfect match. In the example given, H2O2 was the substrate and catalase was the lock. H2O2 was broken down into 2H2O and O2, its products.

1. Enzymes are compare to a lock because of the fact that they work like one. For example, the active site is like the whole or more so were the key will be placed. In this case the substrates acts as the key and at the end a product is made.

1) An enzyme has a lock, the active site, in which the substrate, or the key enters and chemically bonds with it. Then, the substrate is released and usually broken up, releasing products of the reaction.

Enzymes have a hole in the active site where the substrate goes. protein is the type of macromolecule. we need iron to help oxygen go trough out the body. its hemoglobin. competitive is when you use an inhibitor to get space and a allosteric is when it attaches to the active site on enzyme to block the opposite side. one variable could be the temputure and the other could be the ph

Enzymes have active sites and they act like a hole. The substrate fits right into the active site like a key to a key hole. Competitive inhibition is competing for the space while allosteric means different shape which just covers the hole. Enzymes are a macromolecule of proteins. Iron creates hemoglobin in our blood and that is important because hemoglobin delivers oxygen throughout your body. Two independent variables would be pH level and temperature.

1.) An "enzyme" has somewhat of a ditch in it or a hole that is called an "active site". You can say that the active site is like a lock and a substrate is designed to fill in that hole or the key to the lock. Once the substrate fills in the active site it will then produce a product.

Cofactors and coenzyme are the two different factors that could affect the enzyme rate.
