1. The glutamate causes an influx of ca2+ ions into the nerve cell akin to what occurs during depolarization. However, this occurs excessively without regulation (due to excessive stimulation by the glutamate) that eventually causes nerve injury through cytotoxic edema.
2. When the ca2+ levels are lowered during stroke, then nerve cell injury would be obviated hence enabling the chances of restoration of nerve cell function. This would happen because there would be no excess calcium ions to influx when the NMDA receptors are excessively stimulated by the glutamate molecules.
Answer:
Pond
Explanation:
Ponds are inland water bodies that are usually smaller in surface area than a lake and nonflowing in contrast to rivers or streams. However, a pond is a shallow freshwater source that inhabits organisms' life (plants and animals alike).
Due to the shallow state of a pond, light penetrates to the bottom, hence, allowing the constant growth of plant life. Therefore, PONDS are freshwater sources that contains a permanent shallow body of water with plant life throughout.
Answer:
The answer is: Carbon dioxide and water released by cellular respiration are used in photosynthesis.
Explanation:
Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
