In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. ... The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.

What types of materials are expelled from cells during exocytosis?
alex41 [277]

Large molecules such as hormones materials are expelled from cells during exocytosis

<u>Explanation:</u>

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

rosijanka [135]
I am a white bread I am but inside my fellow human and chewed in the mouth and breaks down my carbohydrates and then I become a boules then I am swallowed through the esophagus which pushes me to the stomach which then I digest into chyme and then the stomach secrets it’s juices to break down the protein then I’m pushed to the small intestine dejunume where liver secretes bile to gallbladder then gallbladder secretes it and stores it. Also the pancreas secretes also enzymes to break it down. Then intestine justices break me down then I am sucked up of my nutrients and put into cells and then my remains go to large intestine where water and minerals are absorbed and then I’m sent to the rectum then anus to land in a toilet water to take on a new journey. :) hope this helps so how

The light-independent reactions of plants function to make organic molecules using carbon dioxide as a carbon source. What is th
scoray [572]

Answer:

<h2>NADPH</h2>

Explanation:

Photosynthesis is a biochemical reaction in which glucose is synthesized by green plants and some other green organisms that have chlorophyll molecule. In this reaction carbon dioxide and water are treated as raw materials. This reaction is completed in two steps, in first step water splits by the sunlight and formation of ATP, NADPH and oxygen molecule takes place so-called as a light reaction.

In the second step no light is required and carbon dioxide is reduced by NADPH so-called light-independent reaction. Since in this reaction electron is transferred by NADPH so considered as an electron source in light-independent reaction.

crimeas [40]

In the block to polyspermy, entry of the sperm's contents causes calcium ion levels in the oocyte's cytoplasm to rise, triggering the cortical reaction.

In biology, polyspermy describes the fertilization of an egg by more than one sperm. Diploid organisms normally contain two copies of each chromosome, one from each parent.

The cell resulting from polyspermy, on the other hand, contains three or more copies of each chromosome—one from the egg and one each from multiple sperm. Usually, the result is an unviable zygote. This may occur because sperm are too efficient at reaching and fertilizing eggs due to the selective pressures of sperm competition.

The cortical reaction is a calcium-dependent exocytotic process in which the content of secretory granules is released into the perivitellin space immediately after fertilization, which serves to prevent polyspermic fertilization.
