High Energy electrons are transported from the chlorophyll to other molecules in the chloroplast by?

Reil [10]

Explanation:

High-energy electrons are transported from the chlorophyll to other molecules by electron carriers beginning with pheophytin, P0 (a form of chlorophyll), then A1 phylloquinone etc.

The chloroplast is an organelle attached to the membrane found in plants. This comprises many plasma membrane invaginations called the thylakoid membrane. It contains chlorophyll pigments, called granum in rows, while the organelle's internal areas are called the lumen. Water fills the granum and the stroma is created.

Further Explanation:

<em>During the light reaction: </em>

Photosystem II (PSII) contains pigments which consume light energy. This energy is exchanged between pigments until it enters the reaction core and is moved to P680; this transfers an electron to a higher level of energy where it then travels to a molecule of acceptors.
For those removed from photosystem II, water supplies the chlorophyll in plant cell with substitute electrons. Additionally, water (H2O) divided into H+ and OH-by light during photolysis acts as a source of oxygen along with functioning as a reducer.
The electron moves down the electron transport chain via several electron carriers
The e- is delivered (to PS I) where it has a continuous loss of energy. Such energy drives the drainage of H+ from the stroma to the thykaloid, which results in a gradient creation. The H+ pass down their curve, passing into the stroma by ATP synthase.
ATP synthase converts ADP and Pi to the ATP molecule, which stores energy.
The electron enters Photosystem I where it heads to P700 pigments. It's. This consumes light energy, transfers the electron to a higher energy level, and moves it on to an acceptor electron. This leaves room for another electron which is then replaced by a photosystem II electron.
In the ETC the NADP molecule is reduced to NADPH by supplying H+ ions. NADP and NADPH are vital to the Calvin cycle, in which monosaccharides or glucose-like sugars are produced after several molecules have been modified.

How much weight can a male American Pekin duck carry?

vovikov84 [41]

Answer:

up to 13 pounds.

Explanation:

Their fine meat quality and egg-laying ability has made them the first choice of American duck growers. They are the easiest domestic ducks to process and prepare for meat production. Male Pekins carry a Fall weight of up to 13 pounds, and the females weigh about 7 pounds.

What is the basic difference between simple diffusion and facilitated diffusion across a cell membrane? hints?

Licemer1 [7]

Simple diffusion is the process by which a substance moves across a cell membrane from an area of high concentration to an area of low concentration. Substances that move by simple diffusion are able to diffuse directly across the phospholipid bilayer of the cell membrane. These substances are generally small and neutral, as large or charged particles cannot cross the phospholipid bilayer. Some examples of molecules that move by simple diffusion are carbon dioxide and oxygen.

Facilitated diffusion is the process by which a substance moves across a cell membrane from an area of high concentration to an area of low concentration with the aid of a membrane protein. Substances that move by facilitated diffusion are not able to diffuse directly across the phospholipid bilayer of the cell membrane. These substances are generally large and/or charged. They therefore travel through a protein channel in the cell membrane along their concentration gradient. Some examples of substances that can move by facilitated diffusion are glucose, sodium ions and chloride ions.

The similarities between facilitated diffusion and simple diffusion are:

They both involve the movement of a substance across a cell membrane along its concentration gradient (from an area of high concentration to an area of low concentration).

They are both examples of passive transport, as neither requires energy from the cell to move the substance across the membrane.
