(Q029) Which of the following statements is FALSE? Group of answer choices Formins promote the formation of unbranched actin filaments. Actin filaments are usually excluded from the cell cortex. Integrins are transmembrane proteins that can bind to the extracellular matrix. ARPs can promote the formation of branched actin filaments.

- Actin filaments are usually excluded from the cell cortex

Explanation:

In eukaryotic cells, actin proteins polymerize in order to form filaments. These actin filaments can be localized beneath the plasma membrane, where they form a network that helps to provide mechanical support. This network localized on the inner face of the plasma membrane is called 'cell cortex', which is a specialized structure that is attached to the cell membrane by Ezrin, Radixin and Moesin (ERM) proteins. The cell cortex plays key roles by controlling the cell shape, cell morphogenesis and membrane behavior.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
