Enzymes lower the activation energy needed for a reaction to occur, speeding up the reaction without being consumed or permanently altered in the process. They achieve this by binding to substrate molecules in a specific orientation that promotes the formation of product molecules.

What effect does an increase in pH have on enzyme reaction?
An increase in pH can affect enzyme reactions by altering the charge on amino acid residues in the enzyme, leading to changes in the enzyme's structure and potentially impacting its activity. Each enzyme has an optimal pH at which it functions most efficiently, and deviations from this pH can decrease enzyme activity.
Relate the shape of an enzyme to its ability to help in a chemical reaction?
An enzyme's specific shape allows it to bind with a substrate molecule, forming an enzyme-substrate complex. This interaction positions the substrate in a way that promotes the chemical reaction to occur more quickly and efficiently by lowering the activation energy required. The unique shape of the enzyme's active site is crucial for catalyzing the reaction with high specificity.
What is an enzyme and how does it help speed up a chemical reaction?
An enzyme is a biological catalyst that speeds up chemical reactions by lowering the activation energy needed for the reaction to occur. Enzymes achieve this by binding to specific substrate molecules and facilitating their conversion into products more efficiently than without the enzyme.
What is the relationship between an enzyme and a reactant molecule?
Enzymes bind to reactant molecules, or substrates, at their active site. The active site of the enzyme allows for specific interactions with the substrate, facilitating the chemical reaction to occur. Enzymes lower the activation energy needed for the reaction to proceed, thus increasing the rate of the reaction.
What can affect protein and enzyme function?
Factors such as temperature, pH, and the presence of inhibitors can affect protein and enzyme function. Changes in these conditions can alter the structure of the protein or enzyme, impacting their ability to carry out their specific functions.
After the enzyme catalyzes the reaction is it changed in any way?
The enzyme does not undergo any permanent changes during the catalytic reaction; it simply facilitates the reaction by lowering the activation energy. At the end of the reaction, the enzyme is released unchanged and can participate in further reactions.
How do enzymes affect standard free energy?
Enzymes lower the activation energy required for a reaction to occur, thus speeding up the reaction rate. This does not affect the standard free energy change of the reaction but allows it to reach equilibrium more quickly.
What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
What effect does an increase in pH have on enzyme reaction?
An increase in pH can affect enzyme reactions by altering the charge on amino acid residues in the enzyme, leading to changes in the enzyme's structure and potentially impacting its activity. Each enzyme has an optimal pH at which it functions most efficiently, and deviations from this pH can decrease enzyme activity.
In what way would a defective enzyme affect an organism if it was involved in metabolic reactions that produce ATP?
Non-working enzyme → no ATP → no energy → death.

What does cph4 affect?
There is a metabolic enzyme called 6-carboxytetrahydropterin synthase or CPH4 synthase that acts as a catalyst in the following reaction: 7,8-dihydroneopterin 3'-triphosphate + H2O 6-carboxy-5,6,7,8-tetrahydropterin + acetaldehyde + triphosphate To my knowledge however, it does not affect neurological development in any way.
What can effect how an enzyme works by changing the enzyme's shape?
Factors such as pH, temperature, and the presence of inhibitors or activators can alter the shape of an enzyme, impacting its effectiveness. These changes can affect the enzyme's ability to bind with its substrate and catalyze the reaction, ultimately influencing the rate of the reaction.
How the enzyme amylase affects starch?
Amylase is an enzyme that breaks down starch into simpler sugars like maltose and glucose through a process called hydrolysis. It catalyzes the cleavage of glycosidic bonds in the starch molecule, facilitating its digestion in the body. This allows the body to absorb the simple sugars for energy production.
Describe how the interaction between an enzyme and its substrates change a chemical reaction?
An enzyme binds to its substrate, forming an enzyme-substrate complex. This interaction lowers the activation energy required for the reaction to occur. It brings the substrates into close proximity and orients them in a way that facilitates the reaction, leading to the formation of products.
