In the organelle mitochondria is where most ATP production take place. ATP or adenosine triphosphate is the energy released by mitochondria through electron transport chain.
Answer:
True
Explanation:
They are made out of those cells. They are the red blood cells
The statement that is true about polar covalent bonds is that the electrons are shared unequally. Thus, the correct option for this question is D.
<h3>What is a Polar Covalent bond?</h3>
A Polar covalent bond may be characterized as a type of covalent bond in which the electron density is unevenly shared between the two bonded atoms, due to a difference in electronegativity or due to inductive effects.
According to the context of this question, in a polar covalent bond, the electrons are unequally shared by the atoms and spend more time close to one atom than the other.
This is because of the unequal distribution of electrons between the atoms of different elements, slightly positive (δ+) and slightly negative (δ–) charges develop in different parts of the molecule.
Therefore, the statement that is true about polar covalent bonds is that the electrons are shared unequally. Thus, the correct option for this question is D.

Answer:
Kinases refer to the group of enzymes which catalyze the transfer of phosphate group to their substrate. The phosphate group is usually transferred from high energy phosphate donating molecules such as ATP and GTP.
Addition of phosphate group may activate some proteins or enzymes while it may deactivate other enzymes.
For example, CDK-activating kinase adds phosphate groups to the CDK in order to activate them.
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.
