What else can I help you with?
How many known enzymes does a human cell have?
100
Are many enzymes proteins?
Yes most of the enzymes are proteins. There are a few RNA enzymes known as ribozymes exist. Proteins are all coded in DNA in the nucleus.
Catalyst known as?
enzymes
What nutrient acts as a helper in many different chemical reactions in the body?
Vitamins. They are known as co-enzymes.
What are known as biological catalysts?
Enzymes
What nutrient acts as helper molecules in many different chemicals reactions within the body?
Vitamins. They are known as co-enzymes.
Is a catalyst also known as a hormone?
Nope. Enzymes
What molecules digest starch?
Enzymes known as amylases.
What enzyme breaks down polypetides?
Enzymes that break down proteins are called a protease. There are many different enzymes that break down many different polypeptides. Usually they will end in the suffix "-in".
At what pH do enzymes work best?
Enzymes work best at a pH that is specific to each enzyme, known as its optimal pH. This optimal pH is typically around neutral, or pH 7, for many enzymes found in the human body. However, some enzymes may work best in acidic or basic conditions depending on their specific function.
Which enzyme exhibits the highest catalytic efficiency among all known enzymes?
The enzyme carbonic anhydrase exhibits the highest catalytic efficiency among all known enzymes.
What group of molecules are enzymes?
Most enzymes are proteins. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.
