Answer:

Membrane-bound proteins that use metabolic energy to move ions across the plasma membrane are known as ion pumps and transporters. Pumps creating a membrane potential across the biological membrane which helping ions to move against a concentration gradient.

Ion pumps are classified into two types based on their method which they are using to move:

1) Primary active transport: They are trans-membrane ATpases, for transport ions up a concentration gradient they hydrolyze the ATP to produce energy.

2) Secondary active transport: They transport the molecules across the cell membrane through the electrochemical gradient generated by pumping out of the cell.

Cytochalasins bind actin and block actin microfilament assembly. Cells treated with cytochalasins will not divide. How do cytoch

7nadin3 [17]

Answer:

The correct answer will be option-A

Explanation:

Cytochalasin is the metabolic product released from the fungus. The cytochalasin acts a toxin to the cell as it inhibits the division of the cell.

Cytochalasin act by inhibiting the cytoplasmic separation during cell division as it blocks the formation of contractile microfilaments. The presence of cytochalasin inhibits the elongation of acing filament as it blocks the addition of the monomer to the growing end of the filament.

Since it prevents the formation of the contractile rings and cytoplasmic separation, therefore, option-A is the correct answer.

kvv77 [185]

Answer:

Coagulative necrosis

Explanation:

When cell death occurs due to ischemia or infarction then this is termed as Coagulative necrosis.
During this type of necrosis, cell death occurs in a localized area due to lack of oxygen and other nutrients.
When a two year old swallows watch batteries then these batteries becomes trapped in the digestive system and inside the digestive tract , the positive and negative terminals of the battery gets bridged by the mucosa leading to the production of the electrical current and increase in the pH of the mucosa.
All these condition leads to coagulative necrosis due to which the kidney gets affected and heart failure occurs .
