Answer:

B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.

Explanation:

Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.

In order for fsh to directly affect sertoli cell function, what is the first thing that happens when an fsh molecule is near a s
TiliK225 [7]

A Sertoli cell (a kind of sustentacular cell) is a "nurse" cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis; that is, the production of sperm.

It is activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis, and has FSH receptor on its membranes. It is specifically located in the convoluted seminiferous tubules (since this is the only place in the testes where the spermatozoa are produced). Development of Sertoli cells is directed by the testis-determining factor protein.

jak nazywa sie proces w którego wyniku powstaja chmury : a) parowanie b) skraplanie c) krzepiecie d) topienie​
Tanzania [10]

Answer: b) skraplanie

Explanation:

As part of the hydrological cycle, water is evaporated off of the surface of the earth and turns into the gaseous form of water which is water vapor. With temperatures getting colder as you go higher, the water vapor will begin to condense into water droplets in the process called Condensation.

As this happens, the water droplets will come together and begin to form clouds. This will continue till the cloud gets too heavy for the capacity of the atmosphere and will then fall as rain.
