Answer:

Bacterial flagella is the external structure that is thin, long and filamentous. It is attached to the cell wall of the bacteria which helps in the locomotion of the bacteria. It has three parts a filament, hook and basal body. The basal body is incorporated in the cell membrane.

A flagellum is made up of a protein called flagellin. It is a rigid protein and helps in making the hollow core of the filament by assembling together to form a structure which is cylindrical in shape.

The organization of flagella on bacterial cells is helpful in the identification of bacterial species. Mostly 4 type of organization of flagella is present on bacterial cell that are monotrichous, amphitrichous, lophoyrichous and perithrichous.

In monotrichious bacteria, only one flagella is present on one side, in amphitrichous both side of the cell have an equal amount of flagella. Lophotrichous bacteria have a group of flagella at one side of the cell and amphitrichous bacteria have many flagella distributed equally on its cell.

5. What types of genes change very slowly?
allsm [11]

Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

What is a benifet of using technology to transport water
oksian1 [2.3K]

Answer:

The benefits that we can get in using the technologies of transport water are the following:

 

1.       Less Maintenance Cost

2.       Cheaper cost

3.     There will be knock-on welfares as products will be industrialized with new applications where the price acceptance is much lower

4.     As these technologies progress and learn to treat high measurements of water, we will see cheaper, more filtered treatment systems and we will start to move away from enormous unified treatment systems.

5.     The technologies help to remove any matters from water, microbes, and bacteria

1. List and describe three factors that could possibly affect enzyme activity. 2. Why is it important that cells contain catalas
marta [7]

Answer:

1. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

2. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). It catalyzes the decomposition of hydrogen peroxide to water and oxygen.

3. Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. ... Extreme pH values can cause enzymes to denature.

4. Enzymes are biocatalysts and because of their remarkable properties, they are extensively used in medical diagnosis. ... They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy.

5. The small intestine is a major site for chemical digestion and absorption of key food components, such as amino acids, peptides, and glucose for energy. There are lots of enzymes released in the small intestine and from the nearby pancreas for digestion.

6. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC 3.2. 1.1) was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.

Explanation:

1. Factors Affecting Enzyme Activity

Knowledge of basic enzyme kinetic theory is important in enzyme analysis in order both to understand the basic enzymatic mechanism and to select a method for enzyme analysis. The conditions selected to measure the activity of an enzyme would not be the same as those selected to measure the concentration of its substrate. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

2. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).

4. for clinical applications. Enzymes are the preferred markers in various disease states such as myocardial infarction, jaundice, pancreatitis, cancer, neurodegenerative disorders, etc. They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy.

5. Amylase. Amylase is a digestive enzyme that acts on starch in food, breaking it down into smaller carbohydrate molecules. ... First, salivary glands in your mouth make salivary amylase, which begins the digestive process by breaking down starch when you chew your food, converting it into maltose, a smaller carbohydrate.

6. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC 3.2. 1.1) was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.
