What is the purpose of the electron transport chain in the thylakoid membrane?

Biology
1 answer:
Feliz [49]3 years ago
6 0

Answer:

To produce energy in form of ATP

Explanation:

The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors.  These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP.  Later on these electrons will reach the other photosystem, to produce reducing power.  This is in plants.

Cyclic photosystems also exist, in some bacteria, for example,  and only produce energy as ATP.  They also have an electron transport chain.

Identify which layer of the integumentary system each of the following is most likely to be found and provide a one phrase descr
Zielflug [23.3K]

Answer:

The integumentary system comprises the skin, nails, hair and exocrine glands. The average persons skin weighs a approximately 9Kilograms and spans about  20 square feet.

Phagocytic cells: These are found in the dermis or hypodermis. The skin layer that lies directly beneath the epidermis and above the subcutaneous layer is the <em>dermis</em>. It is made up of fibrous and flexible tissue and is the thickest layer of the skin. It thus gives the skin power and flexibility.

Phagocytic cells are cells within the skin that are designed for detecting, engulfing, and destroying pathogens (such as bacteria and other harmful organisms) and apoptotic cells. Apoptotic cells are cells in the human body that have spent their lifespan and are ready for replacement.

Keratinocytes: This is the most common type of cell in the human skin. It is mostly found on the Epidermis and comprises about 95% of the same.

The Epidermis is the most visible part of the skin. It is the part of the skin which the eyes can see. Its function is mostly protective. It receives all nutrition from the dermis because it does not contain any blood vessels.

Arrector Pili Muscle: Beneath the skin, there are tiny muscles that are attached to the base of a hair follicle at one end and to dermal tissue on the other end. These are known as the Arrector Pili.

Papillae: The dermal papillae comprise a little amount of the dermis. They project out of the epidermis. They aren't always immediately visible on the surface of the skin but tend to be quite obvious when examined under a microscope.

Melanocytes: These are neural crest-derived melanin-producing cells. They are mostly found in the lower layer of the skin's epidermis (also known as the stratum basale), the middle layer of the eye (uvea), the inner ear, the vaginal epithelium, the meninges, the bones, and the core. A black pigment mainly responsible for skin color is melanin.

Paccinian corpuscles: can always be seen in the deep part of the dermis of both glabrous and hairy skin. Structurally, they are very much like the  Meissner's corpuscles.

Paccinian corpuscles can be found in the Periosteum of the bone, capsules of the joints, pancreas, other internal organs, breast, and genitalia.

The lifetime of an intracellular signaling molecule must be short for the cell to be able to cause a change in the concentration
ivann1987 [24]

Answer:

Statement B is false.

Explanation:

PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.

At the level of  polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.

Thus, the correct answer is - option B.
