Enzymes are examples of?
biological catalysts that speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They are specific in their action, often catalyzing only one type of reaction or a set of closely related reactions.
What bioorganic molecule are enzymes made of?
Enzymes are made up of proteins, which are biologically organic molecules composed of amino acids. These amino acids are linked together in a specific sequence to form the unique structure of each enzyme, allowing them to catalyze specific biochemical reactions in living organisms.
Why are enzymes said to be specific?
Enzymes are highly specific in their action. For example, enzyme maltase acts on sugar maltose and not on lactose or sucrose. Different enzymes may act on the same substrate but give rise to different products. For example, raffinose gives rise to melibiose and fructose in the presnce of enzyme sucrase while in the presence of enzyme melibiase it produces lactose and sucrose. Similarly an enzyme may act on different substrates like sucrase can act on both sucrose and raffinose producing different end products.
What does it mean when it says enzymes are specific?

What are the names of some enzymes?
Hydrolases - Hydrolysis of a substrate - digestive enzyme isomerases - change of the molecular form of the substrate - famerase
How do enzymes catalyse reactions?
Enzymes catalyse biochemical reaction by lowering the activation energy.
What does reusable enzymes mean?
Enzymes aren't used up or denatured after they catalyse a reaction.
Is enzymes slow the rate of reaction?
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
Is it possible that the human enzymes can be utilized as a perfume?
I don't think this would have much effect. Enzymes catalyse body reactions such as digestion. You Pheromone perfumes are on the market.
How are enzymes involved in chemical reaction?
Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.
What organ releases sucrose maltose and lactose to break down sucrose?
The organ that releases enzymes to break down sucrose, maltose, and lactose is the pancreas. It secretes digestive enzymes, including maltase and sucrase, which help in the breakdown of these sugars in the small intestine. Additionally, the small intestine itself also produces enzymes that further assist in carbohydrate digestion.
Why enzymes are called hydrolytic enzymes?
Careful! Not all enzymes are hydrolytic. Hydrolytic enzymes catalyse reactions in which there is breaking of molecules (involving the participation of water molecules). There are enzymes which catalyse reactions in which molecules join together to form a larger molecule (condensation reactions)
Why does pepsin not digest sucrose?
Sucrose is a type of carbohydrate. Pepsin is a protease, so it can only digest proteins, because enzymes are specific to one kind of molecule. Sucrose would be broken down by a carbohydrase.
What do organisms contain to catalyse hydrolysis reactions in cells?
Organisms contain enzymes to catalyze hydrolysis reactions in cells. Enzymes are biological catalysts that speed up chemical reactions, such as breaking down large molecules into smaller components through hydrolysis.
Is sucrose a substrate?
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides.
What is proteins enzyme?
All enzymes are chemically proteins. but not all proteins are enzymes. Enzymatic proteins catalyse the biochemical conversion of substrate in to product. Good example is amylase that digest starch or glycogen to produce glucose.
What is the end product of arginine hydrolysis?
The end products of the hydrolysis of Arginine are Orthinine and urea, several enzymes catalyse this reaction the easiest to remember is arginase.
