Why will antibotics work against bacteria but not viruses

1 answer:

4 0

Antibiotics work by affecting things that bacterial cells have but human cells don't. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall. Unfortunately, they are less effective against viruses than they are against bacteria. Antibiotic drugs kill bacteria by disrupting their cell walls. But virus' external covering, known as the viral envelope, is almost identical to the host cell's membranes, making them difficult to target

Fittoniya [83]

Chemical bonds between glucose molecules in starch that are easily broken by human digestive enzymes are called alpha bonds.

How is starch broken down into glucose?

When you consume starchy meals, an enzyme called amylase located in your saliva and small intestine breaks down the starches into sugars like glucose, maltotriose, and maltose.
Other enzymes, such as maltase, lactase, sucrase, and isomaltase, further break down these compound sugars into simple sugars.

What is alpha and beta bond?

The 1,4 alpha and 1,4 beta glycosidic linkages are the two different forms of glycosidic bonds.

When the OH on the carbon-1 is below the glucose ring, 1,4 alpha glycosidic bonds are created, whereas when the OH is above the plane, 1,4 beta glycosidic bonds are created.

Studentka2010 [4]

Answer:

INVASIVE species

Explanation:

In biology, an organism is said to be INVASIVE if the organism is foreign to a particular region or habitat and possess the unpleasant ability to proliferate or grow rapidly to the point of competing with local species of organisms.

According to this question, humans are said to introduce organisms that have the ability to harm the local flora and fauna. Hence, these organisms are INVASIVE SPECIES because they are foreign to that place and cause damage in their new environment.

What gas is a reactant in cellular respiration

pochemuha

Answer:

Explanation: Although cellular respiration has multiple parts, the basic chemical equation is:

Answer: Oxygen

Explanation: Oxygen + Glucose (sugar) = Carbon Dioxide + Water + Energy (ATP)

This equation is often broken into two parts, the reactants and the products. Reactants are the molecules that begin cellular respiration, in this case that would be oxygen and glucose. Products are what forms during cellular respiration. Here, the products are carbon dioxide, water, and energy. As the focus of this lesson is on the reactants of cellular respiration, oxygen and glucose, let's take a look at those.

Reactants--

The first reactant in the equation for cellular respiration is oxygen. Most people are familiar with oxygen since it's the primary gas needed for sustaining our lives. We obtain oxygen by simply breathing. Oxygen is highly reactive and therefore perfectly suited for driving chemical reactions such as cellular respiration. However, people may be less familiar with the second reactant in our respiration equation: glucose.
