What else can I help you with?
The active site of an enzyme is the location of substrate attachment?
The active site of an enzyme is where the substrate binds and undergoes a chemical reaction. It is a region on the enzyme molecule where catalysis takes place. The active site has a specific shape that allows it to interact with the substrate with high specificity.
A chemical reaction in a living cell occurs in the presence of a specific protein molecule?
The specific protein molecule in a cell acts as a catalyst, facilitating the chemical reaction to occur more efficiently or at a faster rate. The protein molecule binds with the reactants, stabilizes the transition state, and lowers the activation energy required for the reaction to proceed. Without the presence of this protein molecule, the reaction may occur, but at a significantly slower rate.
Which part of the photosynthetic cycle involves an enzyme taking a molecule of NADP plus and adding two electrons?
The light-dependent reactions of photosynthesis involve an enzyme called ferredoxin-NADP+ reductase taking a molecule of NADP+ and adding two electrons to form NADPH. This process occurs in the thylakoid membrane of the chloroplast.
Does a substrate molecule need and enzyme molecule?
No substrate molecules can react on their own, however without enzymes this occurs at such a slow rate that, chemical reactions required to sustain life would not occur fast enough and the organism would die.
What is the role of RuBp in Calvin cycle?
It is an enzyme that triggers the carboxylation (combining of carbon dioxide) of ribulose biphosphate in the stroma of chloroplasts in plants. This carboxylation is the first step of the light-dependant reaction that occurs in plants and this light-dependant reaction is the second stage of photosynthesis.
How does an enzyme change how a reaction occurs?
An enzyme speeds up your reaction in your body.
What occurs to a molecule of the enzyme trypsin AFTER human pancreas binds to a molecule of protein?
Trypsin is an enzyme that is produced in the pancreas. After the human pancreas binds to a molecule of protein, auto catalysis occurs to a molecule of trypsin.
A chemical reaction in a living cell occurs in the presence of a specific protein molecule The concentration of this protein molecule remains the same before and after the reaction This protein mole?
This protein molecule is likely an enzyme, which facilitates the chemical reaction by lowering the activation energy required for the reaction to occur. Enzymes remain unchanged after the reaction and can be reused to catalyze multiple reactions. They are specific to the reaction they catalyze and are essential for the proper functioning of the cell.
The active site of an enzyme is the location of substrate attachment?
The active site of an enzyme is where the substrate binds and undergoes a chemical reaction. It is a region on the enzyme molecule where catalysis takes place. The active site has a specific shape that allows it to interact with the substrate with high specificity.
Why are enzymes three dimensional shape so important?
An enzyme's three dimension shape is important to the binding that occurs between the enzyme itself and its specific substrate, forming the enzyme-substrate complex. In order for the enzyme to create a reaction it is important that the shape of the enzyme binds the substrate to the active site where the chemical reaction occurs. One other thing to consider is the shape that the enzyme takes that allows only its specific substrate to bind and not any other molecule.

The specific protein molecule in a cell acts as a catalyst, facilitating the chemical reaction to occur more efficiently or at a faster rate. The protein molecule binds with the reactants, stabilizes the transition state, and lowers the activation energy required for the reaction to proceed.

What is an active site and what is its relationship to an enzyme?
an active site in an enzyme is the area that breaks the bond in its substrate. E.g. a maltose molecule's glycocide bond is broken by the active site in a maltase enzyme.
Which part of the photosynthetic cycle involves an enzyme taking a molecule of NADP plus and adding two electrons?
The light-dependent reactions of photosynthesis involve an enzyme called ferredoxin-NADP+ reductase taking a molecule of NADP+ and adding two electrons to form NADPH. This process occurs in the thylakoid membrane of the chloroplast.
What is the name of the Place on an enzyme where reaction occurs?
"Inside your mouth. It's like the saliva that you won't be able to taste food without."Err... lol.A enzyme reacts with a substrate at the enzyme's active site.
When an enzyme catalyzes a reaction do Substrates bind in the active site or do Products bind in the active site?
Substrates. Once the enzyme and the substrate combine, on the product is created.
Does a substrate molecule need and enzyme molecule?
No substrate molecules can react on their own, however without enzymes this occurs at such a slow rate that, chemical reactions required to sustain life would not occur fast enough and the organism would die.
