Answer:

Their saliva contains an anticoagulant and proteins. The proteins are foreign substances that trigger the body's immune system. To fight them the body's immune system releases histamine, a compound that helps white blood cells get to the affected area. Histamine is what causes the itchiness, inflammation, and swelling

serious [3.7K]

Answer:

1. Glycolysis

2. Pyruvate

3. Mitochondria

4. Acetyl CoA

5. Krebs (citric acid) cycle

6. Electron transport system

Explanation:

The cellular respiration is the process which converts the food material to energy molecule in the form of ATP.

The cellular respiration begins with the process of glycolysis which converts the glucose molecule to two molecules of pyruvate in the cytosol.

The pyruvate molecule then enters the mitochondria where it gets converted to Acetyl CoA through pyruvate decarboxylation reaction. The Acetyl CoA then enters the Krebs cycle which converts the acetyl CoA by adding the oxaloacetate producing the reducing equivalents.

These reducing equivalents get reduces and the free electron enters the electron transport chain which finally forms the ATP molecule.

Serpins are naturally occurring proteins that serve as serine protease inhibitors. Serpins bind to the enzyme and are cleaved, b

Veseljchak [2.6K]

Answer:

Explanation:

The serpins are components of human plasma and its mutations result in numerous genetic diseases, such as caused by the deficiency of α 1 -antitrypsin. They are proteins of high molecular mass (350-500 amino acids) and have been identified in numerous organisms, from viruses to mammals. The serpins interact with the target enzyme by a similar mechanism on a substrate, although an irreversible interaction where the bond occurs serpin adopts different conformations to interact with the protease target, causing a deformation of the active site of the protease.

The mechanism of inhibition of Trypsin by serpin can be seen in the image below.

<h3>☣ Question -:</h3>

Which of these equation is the correct one for fermentation?

❍ Glucose + oxygen → carbon dioxide + water

❍ Glucose → lactic acid

❍ Glucose → ethanol + carbon dioxide

<h3>☣ Explanation -:</h3>

To understand this first we should know what is fermentation.

<u>What </u><u>is </u><u>fermentation</u><u>?</u>

A process of chemical change in food or drink because of the action of yeast which may cause it to produce bubbles or heat, or turn sugars in it into alcohol.

<u>Equation -:</u>

$\small\sf{C_{6}H_{12}O_{6} \rightarrow2C_{2}H_{5}OH + 2CO_{2}}$

Which means

Glucose → ethanol + carbon dioxide

Hence opition c is the correct answer.
