Biology
1 answer:
Hoochie [10]3 years ago
6 0

Answer:

B

Explanation:

The dermis is the layer of skin below the epidermis. Below the dermis is the subcutaneous layer. It contains connective tissue from collagen and elastic fibers giving skin its elasticity. It contains nerve fibers sensitive to heat and touch. Glands - like sebaceous & sweat glands, hair follicles, and blood capillaries that supply the skin, are found in this layer.

When the ATP synthase molecules are open, the hydrogen ions move out of the thylakoid. How does the cell use the kinetic energy
morpeh [17]

The synthesis of ATP is based on energy conversion, via conformational changes of the subunits.

A proton gradient on either side of the membrane into which the ATP synthases are inserted is necessary for their operation, which implies that the synthesis of ATP can not be done independently of a membrane. Within the mitochondrial inner membrane, it is the respiratory chain that provides the pH gradient by injecting protons into the intermembrane space during the transfer of electrons from one complex to another. At the level of the thylakoid membrane, it is the photosynthetic chain that injects protons into the lumen.

In eukaryotic cells, the message from the DNA must be removed from the nucleus before it can be read and used to make proteins.
Crank

Answer:

The correct answer is A protein production can occur much faster in prokaryotic cell since the cell does not have to get the message stored in the DNA out of the nucleus.

Explanation:

protein biosynthesis or translation occur in both Prokaryotes and Eukaryotes.

                In prokaryotic cell both transcription and translation occur inside the nucleus but in case of Eukaryotic cell transcription occur in the nucleus whereas translation occur in the cytoplasm.

         In case of eukaryotic cell mRNA processing occurs which involves 5 prime capping, 3 prime tailing and splicing but in case prokaryotic cell no such processing occurs.

                  As a result protein production occur much faster in prokaryotic cell than that of eukaryotic cell.
