1. what is the chemical reaction that occurs when hydrogen peroxide is broken down by the enzyme catalase? what is the evidence that a chemical reaction has occurred?
2. use the induced fit model to describe what occurs during this enzyme reaction. how do enzymes relate to activation energy?
3. in living things, most chemical reactions occur near ph 7, and changes in ph do not normally occur. describe how buffers maintain a ph of 7 in the human body.
4. enzymes are proteins. summarize in 2 or 3 paragraphs the structure and functions of proteins in living things. include the types of chemical bonds and specific information about enzymes.

Explanation:

1.)The chemical reaction that occurs when hydrogen peroxide is broken down by the enzyme catalase is the chemical reaction the is "Decomposition reaction" i.e breaking down of Hydrogen peroxide into Water and Oxygen.

The Evidence that the reaction has occurred is that there will be ""Oxygen Gas Bubbles Escape and foam will be created""

2.)The induced fit model describe the reaction that the substrate induce change of the shape of the active site

2H2O2 >2H2O+ O2

SUBSTRATE +ACTIVE SITE (ENZYME) >ENZYME SUBSTRATE COMPLEX

HYDROGEN PEROXIDE(Catalase)>WATER+OXYGEN GAS

Catalase lowers the activation energy or the amount of energy required for a reaction because it is an enzyme.

3.)The buffer solution is maintained in human body by this reactions;

Bicarbonate ion (HCO3), Carbon dioxide (CO2) and (Carbonic acid (H2CO3) are solution that will regulate the PH in humans, Carbononic acid is produced when the bicarbonate ions react with with hydrogen ions, then then there is removal of Hydrogen ion therefore Phy is regulated in the blood

Also the lungs create a balance but the release of Carbon dioxide , there is a excretion of acids or base into the blood by

the kidney.

4.) proteins are reffered to as building block of life. They are very essential and they contribute to the growth , functionality and development of the body.

They are molecules from amino acid and form basis of living tissues.

They speed up chemical reaction in the body because they are also enzymes.

The structure of proteins is the arrangements of atoms in chain of amino acids in three dimensions

The bonds that exist in proteins is reffered to as peptide bond. A peptide bond belongs to a category of covalent bond,

what in the weirdo : o

i got you i did it ya know what it is just needing to fill this in for a quick task!
