Salivary amylase is an enzyme that breaks down starch. The optimum or best pH for this reaction is 6.7. Which of the following would not have an effect on a reaction involving this enzyme?
. Amount of substrate
. Enzyme concentration
. Maintaining the pH of the reaction at 6.7.
. Decreased temperature of reaction temperature by 10 degrees C.
Answers
Answer:
:-) maintaining the pH of the reaction at 6.7
Explanation:
hope this helps
A splitting enzyme generated by the salivary glands is called salivary amylase. It assimilates the starch element of the food into small molecules of maltose.
The correct answer is:
Option C. Maintaining the pH of the reaction at 6.7
The explanation for the answer is:
The degree of enzyme activity and its purpose depends on the concentration of the substrate present.Enzyme concentration influences the reaction as increased enzyme amount will result in the reaction to speed up.The enzyme action depends on the temperature as the drop in the temperature will reduce the rate of reaction.Therefore, maintaining the pH of the reaction at 6.7 will not affect the reaction.

Cellular respiration classified as________respiration,occurs in the__________.
Answers
Answer:
1.a combustion reaction
2.inside of cells
Explanation:
Although cellular respiration can be classified as a combustion reaction (thanks to its release of energy in the form of heat), because it occurs inside of cells, the energy is released in slow bursts, and only after a series of reactions and processes. As cellular respiration occurs, it produces CO2, carbon dioxide, as a waste product.

A. The event represents DNA translation in the smooth endoplasmic
reticulum.
B. The event takes place in the bacterial cell.
C. The event produces genetically identical daughter cells.
D. The event provides genetic diversity in eukaryotic cells.
Answers
The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.
The given event in the diagram is known as crossing over which takes place during the process of meiosis.
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in the recombination of the genetic material and creates a new genetic combination.Thus, genetic variations occur which can be beneficial to the offspring.Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.
