When are enzymes used?
Enzymes are used in almost every biological reaction that takes place in an organism to expedite the process.
Where does light reaction occur in a of the chloroplast?
It takes place on thylokoid membranes.Dark reaction takes place in stroma.
What substance takes place in an enzymatic reaction but does not change shape?
Enzymes. Substrates react with the active site of the enzyme and are broken down. Enzymes stay the same throughout the reaction.
How does enzymes catalyze a chemical reaction?
by lowering activation energy to increase the reactionEnzymes are biological catalysts, and can hence lower the activation energy barrier of the reaction that it catalyses. Enzymes do this in several ways:1) Enzymes can provide a suitable environment for the reaction to take place. The active site of a enzyme can be highly acidic (pH
How does concentration affect enzymes?
The greater the concentration of enzymes, the high possibility that a molecule will bind to the active site, so the faster a reaction takes place.
How do enzymes work what do they lower?
Enzymes function when they lower the activation energy. That means it takes less energy for the reaction to work.
Where does the dark reaction of the photosynthesis occur in?
It is not dark photosynthesis.It is dark reaction.It takes place in stroma.
Are enzymes permanently changed in the chemical reactions they aer involved in?
No, enzymes are not permanently changed in the chemical reactions they are involved in. Enzymes are catalysts that facilitate chemical reactions by lowering the activation energy, and they remain unchanged after the reaction takes place. They can be used repeatedly in multiple reactions.
What happens when gain of oxygen takes place?
A loss of electrons occur, an oxidation reaction.
Where does pyruvate processing occur?
Pyruvate processing occurs in the matrix of the mitochondria
Why are many enzymes involved in the digestive system?
There are many different types of enzymes because each type have a differently shaped active site (the place where the reaction takes place) and the reaction can only happen if the active site is the right shape for the food molecule. eg. Protease enzymes break down proteins.
What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
