|
Enzymes supply the oxygen necessary for the reactions
|
|
|
Enzymes change reactants from solid to liquids during the reactions.
|
|
|
The reactions take up too much space in the cell if the enzymes are missing.
|
|
|
The reactions are too slow to meet the needs of the cell if enzymes are missing.

Detailed explanation-1: -Answer: D-The reactions are too slow to meet the needs of the cell if enzymes are missing. Most commonly, enzymes accelerate biochemical reactions by lowering the amount of activation energy required.
Detailed explanation-2: -First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.
Detailed explanation-3: -Enzymes are biological catalysts which speed up biochemical reactions. According to the most widely accepted theory, enzymes bind to the substrate molecule and form a transition state. During the progress of a reaction the substrates are separated from products by an energy barrier which the substrates need to cross.
Detailed explanation-4: -Enzymes are biological catalysts produced by living cells. They differ from other catalysts in being highly selective and specific. Almost all enzymes are globular proteins. They are very specific for a particular reaction and a particular substrate.
Detailed explanation-5: -Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems. Enzymes in our blood can also help healthcare providers check for injuries and diseases.
