What is lactase used for?

Lactase improves the digestion of milk by some people who lack the enzymes, aka lactose intolerance.


Why did the enzyme lactase react with lactose but not sucrose?

Because, lactase breaks beta(1-4) glycosidic bonds between a galactose and a glucose, while sucrose molecule is formed by a dimer of a glucose and a fructose linked by an alpha(1-2) glycosidic bond.


What indicates how much of each reactant will be used up in a reaction?

the coefficients of a balanced reaction


Why is lactase used at relatively low temperatures in food processing?

The lactase enzyme molecules last longer at lower temperatures as there is less denaturation. The energy cost is lower as less energy is used to heat the surroundings. The low temperature can also reduce milk spoilage by reducing bacterial growth. It can control the rate of reaction as well where products are formed more slowly.


How can one Tell how much of a reactant will be used in a reaction?

The ratio of the coefficients tells the ratio of moles of reactants used in the reaction.


How does one determine how much of a molecule is produced in a reaction?

The coefficients and molar masses are used to calculate amounts of molecules.


What type of chemical reaction must occur for electrons to flow from one molecule to the next and supplies the energy for metabolism?

The type of chemical reaction required for electrons to flow from one molecule to the next and provide energy for metabolism is a redox (reduction-oxidation) reaction. In this reaction, one molecule acts as a reducing agent, donating electrons, while the other molecule acts as an oxidizing agent, accepting the electrons. This transfer of electrons generates energy that can be used by the body for various metabolic processes.


How doe one determine how much of a molecule is produced in a reaction?

How can you tell from diagrams that sucrase is not used during the chemical reaction?

you can tell because you can tell the defintion of the sucrease on google and answer it there and if not go on the interent or ask your teacher for help


How is water used during light reactions?

Water is used as a H+ donor.A water molecule is broken using light energy.and electrons released are donated to oxidized reaction centre.


What do you think the molecules are with the -ase endings on them?

-ase is a common suffix used to name various enzymes. So, as an example, a nuclease is an enzyme that cleaves nucleic acids and a telomerase is an enzyme that extends the telomeres. Both produce different outcomes yet both end with -ase.


The ATP molecule is not used in?

The ATP molecule is not used in excretion process. This is a molecule that will be used in cellular respiration to store energy.
