How many 02 molecules are required for two glucose molecules to undergo cellular respiration?
jekas [21]

sleet_krkn [62]

Answer:

The correct answer is option - D. phosphorylation.

Explanation:

The CARD11 or caspase recruitment domain-containing protein 11 is a gene that provides instructions for gene expressing to make a protein in the function of lymphocytes in the immune system. Lymphocytes like B and T cells are activated with the help of cascade reactions in which these genes provide information.

The protein that activates is PKC which is a kinase enzyme that implicates that the process that activates CARD11 is phosphorylation.

Why must the bonds of these molecules be broken before anything else happens?
ser-zykov [4K]

Answer:

Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.

Explanation:

Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. Chemical reactions can occur spontaneously or require an outside trigger such as an input of energy. Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
