<h2><u>These cells are found in the phloem of the flowering plants. They shift sugar and amino acids in and out of the sieve elements. In the leaf (source tissue), the companion cells make use of the transmembrane proteins for the uptake of sugar and amino acids by active transport.</u></h2>

Blockage of the common hepatic duct would interfere with digestion of
Lapatulllka [165]

Answer:

B) fats

Explanation:

Common hepatic duct is s the part of the biliary tract which means that is involved in the secretion of bile.

Bile salts secreted from the bill have an important role in emulsification of lipids (fats). They have the ability to aggregate around lipids thanks to their amphipatic nature. Amphipatic nature means that they have hydrophobic side which binds directly to lipids and hydrophilic side which are faced outwards. Lipids enveloped with bile salts are called micelles.

Formation of micelles increases the surface area of fat, which is appropriate for the the action of the enzyme pancreatic lipase (perform digestion of triglycerides).

Bad White [126]

The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.

<h3>What is antibiotic?</h3>
  • Antibiotics from the key class of glycopeptides can stop this process.
  • Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.
  • Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.
  • The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.
  • Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
  • The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.
