Monosaccharides from polymers through the formation of ———— bonds
Alex_Xolod [135]
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.

Enzymes are pH and temperature specific.Which model shows the relationship between the reaction of velocity of an enzyme and tem
sasho [114]

Answer:

The rate at which an enzyme catalyses a particular reaction is calculated by the amount of substrate being used up. The concept of a chemical reaction is that the substrate is converted into product with the help of an enzyme.

Rate of reaction= Amount of substrate utilized or product formed/ Time taken

Explanation:

Temperature is an important factor in the deciding of a rate of reaction. The velocity of an enzyme <u>increases with an increase in temperature</u> until and optimum temperature is achieved. After that, the velocity of an enzyme starts <em>decreasing</em> since the enzyme starts to get denatured.

Enzymes work best at a <em>specific pH</em>. If there are changes in pH, the active site of an enzyme gets modified and the rate of reaction decreases. Certain enzymes like pepsin which is in our stomach works at an acidic pH of 2.0.

The tendency for energy to be lost as heat during the transformation of organic matter is support for what concept?
leonid [27]

Answer:

a. Entropy

Explanation:

Entropy is the measure of the degree of disorder of a system, being a measure of the unavailability of energy. Rudolf Clausius was the first to use the term Entropy in 1865. Entropy would be the measure of the amount of thermal energy that cannot be reversed into mechanical energy (cannot perform work) at a given temperature.

Because of this concept, we can understand that the tendency of energy to be lost as heat during the transformation of organic matter supports the concept of entropy.
