I need to know the hypothesized enzyme
worty [1.4K]

Answer:

Hypotheis:

<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>

  • <u>A- Pepsin</u>
  • <u>B- Amylase </u>
  • <u> C- thermophilic enzyme</u>

Explanation:

Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.

Each enzyme provided has its own optimal temperature and pH values.

  • Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
  • Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4  glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
  • Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH  is typically low i.e. acidic due to the hydrochloric acid in digestive juices.

Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.

State two ways in which endocrine glands and exocrine glands differ.
denis-greek [22]

Answer:

The two major differences lies in the function and support system.

Explanation:

The two major differences between an endocrine and an exocrine system are as follows –  

a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.  

For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.

b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
