What goes in and out of a cell respiration?

The chemical equation of cellular respiration is C6H12O6 + 6 O2 + 6 H20 > 6 C02 + 12 H20. Meaning glucose, oxygen, and water go into the process with carbon dioxide and water being produced by cellular respiration.            

Hope this help

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
