Answer:
RER is involved in protein synthesis, folding, transport and modification.
Explanation:
The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.
Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.
I think it’s C explanation : i learned this a while ago
This affects facial development and it's a change in the gene in chromosome 5
Genetic expression. The genetic code codes for proteins. The information of the DNA is 'translated' into a chain of amino acids that forms a protein. ... The mutation that causes phenylketonuria disrupts the ability of the body to break down the amino acid phenylalanine.
During exercise, body requires more energy, to meet energy requirement, it uses up blood sugar at a faster rate. As a result blood sugar falls. In this situation cells in the pancreas secrete hormone glucagon. Glucagon directs the liver to convert stored glycogen to sugar. This makes sugar more available in the bloodstream which causes the blood sugar to rise. Hormone Insulin and glucagon work in sync. Glucagon instructs with the liver to raise blood sugar, while insulin lowers blood sugar.
In this way the body of Claire maintains the sugar balance from breakfast until lunch.
