Question

The following descriptions apply to either mitochondrial import or nuclear import. Choose all the statements that apply to mitochondrial import. a. The signal sequence is recognized and bound by a receptor protein in the organelle's outer membrane. b. ATP hydrolysis is required c. GTP hydrolysis is required d. Chaperone proteins are involved e. The imported protein enters through a pore that is large enough to allow ions and water molecules to traverse freely.

Answer 1

Answer:

Option-(A):The signal sequence is recognized and bound by a receptor protein in the organelle's outer membrane.

Explanation:

• The mitochondria are also termed as the "power house's" of the cell structures, as there is more to create energy for the body inside the cell organelle. However, there are certain amino acid chains or simply the proteins which are required for sustaining the over all structure of the cell's organelle. As, there are some protein on the outside of the organelle known as porin.
• While, the organelle itself is involved in the electron transport chain that occurs inside the cell body for generation of the optimum level of energy for the organism to carry out various functions for its survival.
