It is necessary to phosphorylate a glucose molecule so as to trap glucose inside the cell, to make ATP, and to facilitate enzyme building. When insulin is released from the pancreas after a meal, it signals the tissues to uptake glucose. When glucose enters the cells via glucose transporters, there is a chance for them to leave the cell. If the body is in need of energy, and the breakdown of glucose will provide that energy, the body does not want the glucose to leave the cell and that is why the glucose is phosphorylated by ATP to become glucose-6-phosphate, which now bears a charge.
Answer:
Là những biến đổi số lượng xảy ra ở một hoặc một số cặp nhiễm sắc thể hoặc toàn bộ nhiễm sắc thể của mỗi loài. Đột biến nhiễm sắc thể bao gồm 2 loại:
+ Đột biến cấu trúc nhiễm sắc thể.
+ Đột biến số lượng nhiễm sắc thể.
Explanation:
Hi,
"This is because water has a high heat capacity, which means it absorbs a lot of energy in order to increase in temperature (thus releases a lot of energy when it decreases in temperature). This means water can absorb a great deal of the energy on hot days, keeping the surrounding air cooler, and release a lot of energy to the air on cool days, keeping the air warmer"
Have a great day!
Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.
Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
- This leaves a partial negative charge on it.
- The other electron then becomes partially positively charged.
- We can then say, the more electronegative specie undergoes reduction.
- The less electronegative one undergoes oxidation.

TRUE !
there are rain forests in Oregon & other places near buy. Also, just wanted to let you know, don’t come for my head if this answer is incorrect.
KINDEST REGARDS !
