Open Ended Identify factors that can influence<br> enzyme activity. Describe the effect of each.
expeople1 [14]

<u>Temperature, pH, enzyme concentration, substrate concentration, and the existence of any inhibitors or activators</u> are a few of the variables that influence enzyme activity.

  • The rate of the reaction increases proportionally as the enzyme concentration rises. When diagnosing disorders, this feature is utilized to gauge the serum enzymes' activity.
  • The enzymes are highly sensitive to heat changes because they are proteins. Unlike typical chemical processes, enzyme activity is temperature-dependent. Each enzyme has a certain temperature range where it is more active, as you have seen. The ideal temperature, which falls between 37 and 40 degrees Celsius, is at this point.
  • When there is a certain amount of enzyme present, the rate of the enzymatic reaction rises as the concentration of the substrate rises until a limiting rate is achieved, after which additional increases in the concentration of the substrate have no effect on the reaction rate.
  • The most accurate way to estimate a solution's hydrogen ion concentration (H+) is to use the potential of hydrogen (pH). Additionally, it establishes whether the liquid is basic, acidic, or neutral. In general, liquids with a pH of 7 or lower are classified as acids, whereas liquids with a pH of 7 or higher are classified as bases or alkalines.
  • For optimal activity, several enzymes need specific inorganic metallic cations, such as Mg2+, Mn2+, Zn2+, Ca2+, Co2+, Cu2+, Na+, and K+. Anions are also occasionally required for enzymes.

polet [3.4K]

Answer:

The correct answer is - diatom (protist)

Explanation:

The characteristic described by the professor is most similar to the characteristic of aquatic protist - diatoms. Diatoms are the aquatic protist fall into the eukaryotic type of organisms.

These organisms are single-celled and can not swim on their own. They are a primary producer as they do not depends on others for their food and energy and synthesized themselves.

Some autoimmune disorders are thought to be caused by _________, which occurs when an infectious agent is composed of antigens w
EastWind [94]

Answer: adaptive immune response

Explanation:

Autoimmune disorders are caused by different microoorganism and drug which manipulates the immune system in a way that immune system become unable to recognise between self antigen and foreign antigen. In that case immune system treats foreign antigen as self antigen which cause systemic or organ specific damage.

The exact cause of autoimmune disorders is unknown and hence it is  thought that it is caused by adaptive immune response which builds against self antigens and causes damage to the cells.

Hence, some autoimmune disorders are thought to be caused by adaptive immune response.
