It indicates that trypsin is an enzyme that cuts proteins at lysine and arginine peptidic linkages, resulting in the production of 4 and 15 polypeptides, respectively, while cyanogen bromide hydrolyzes methionine residues with high efficiency.

<h3>What are enzymes?</h3>

Enzymes are proteins that hasten chemical reactions and act as biological catalysts. The chemicals that interact with enzymes are known as substrates, and the enzyme converts the substrates into other molecules known as products. Enzyme catalysis is required for the majority of metabolic processes in the cell to proceed at speeds quick enough to support life. Enzymes are required for each step in the catalysis of metabolic pathways. It is known that enzymes catalyze more than 5,000 different kinds of biological reactions.

Can You Tell?<br> Pepsinogen is released in the stomach. Why can't it digest stomach walls?
miv72 [106K]

Answer:

Specific cells within the gastric lining, known as chief cells, release pepsin in an inactive form, or zymogen form, called pepsinogen. By doing so, the stomach prevents the auto-digestion of protective proteins in the lining of the digestive tract.

Describe differences between conduction and convection give examples
nevsk [136]

Explanation:

Both conduction and convection are both forms of heat transfer from one place to another.

  • In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
  • Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
  • Heat transfer in conduction is quite slow compared to convection which is much faster.

Example of conduction is heating of iron pot when cooking

Example of convection is the refrigerating system.

An analytical chemist is titrating 118.3 mL of a 0.3500 M solution of butanoic acid (HC3H7CO2) with a 0.400 M solution of KOH. T
TEA [102]

Answer:

pH = 12.33

Explanation:

Lets call HA = butanoic acid and A⁻ butanoic acid and its conjugate base butanoate respectively.

The titration reaction is

HA + KOH ---------------------------- A⁻ + H₂O + K⁺

number of moles of HA :   118.3 ml/1000ml/L x 0.3500 mol/L = 0.041 mol HA

number of  moles of OH  : 115.4 mL/1000ml/L x 0.400 mol/L  = 0.046 mol A⁻

therefore the weak acid will be completely consumed and what we have is  the unreacted strong base KOH which will drive the pH of the solution since the contribution of the conjugate base is negligible.

n unreacted KOH = 0.046 - 0.041 = 0.005 mol KOH

pOH = - log (KOH)

M KOH = 0.005 mol / (0.118.3 +0.1154)L = 0.0021 M

pOH = - log (0.0021) = 1.66

pH = 14 - 1.96 = 12.33

Note: It is a mistake to ask for the pH of the <u>acid solutio</u>n since as the above calculation shows we have a basic solution the moment all the acid has been consumed.
