Any techniques/ methods used in Biotechnology
BIOTECHNIQUES
It is a common process in chemistry and biochemistry laboratories.
BUFFER PREPARATION
It is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid.
BUFFER SOLUTION
PH value means
POTENTIAL OF HYDROGEN
are used to help maintain a stable pH value of another solution that is mixed with the buffer.
BUFFER SOLUTIONS
a pH value of 7 is neutral, and a pH value of more than 7 to 14 shows increasing ________
Basicity
Any solution that has a pH of less than 7 is considered
ACIDIC
Any solution that has above a pH of 7 is called
BASIC
It is used to rank solutions in terms of how acidic or how basic they are.
PH SCALE
Featured solution for convenient & accurate buffer preparation.
METTLER TOLEDO
They are natural catalysts (biological catalysts) in the form of proteins.
ENZYMES
It is defined as “a substance that increases the rate of a chemical reaction without being itself changed in the process.”
CATALYST
They are produced by living organisms to increase the rate of an immense and diverse set of chemical reactions required for life.
ENZYMES
Who is the french chemist that discovered the first enzyme in 1833?
Anselme Payen
German physiologist________ ________ first used the term enzyme, which is Greek for “in leaven”, to describe this process.
Wilhelm Kuhne
What do you call the fist enzyme?
DIASTASE
In 1897, he found out that juice of ground and pressed yeasts cells could ferment sugar
1897
He discovered that enzymes are proteins. (1926)
James Sumner
It is defined as the energy that must be added to cause molecules to react with one another. It is the minimum amount of energy required to start a reaction.
ACTIVATION ENERGY
It is a set of biochemical reactions on which the entire life of living organisms depend.
METABOLISM
Biochemical reactions in which larger molecules are broken down.
CATABOLISM
Biochemical reactions in which larger molecules are synthesized.
ANABOLISM
It affects the cleavage of the substrate by the addition of water.
HYDROLASES
They catalyze the transfer of reactive groups from one compound to another.
TRANSFERASES
