Answer:
Structurally, the ribosome comprises of two major parts: The small ribosomal units and the large ribosomal units. Each unit contains ribosomal Ribonucleic acid molecules, which is usually one or more than one called rRNA. Each unit also contain ribosomal protein, rproteins. Each of these components are very important for the translation of messenger RNA into proteins encoded by the RNA.
Explanation:
The ribosome and its components are generally referred to as translational apparatus. The small subunit of the ribosome is effective in reading the codes encoded on the mRNA, which . The large subunit is needed to actually join the amino acids needed to form the right protein (or polypeptides). The proteins within the ribosome is used to act as a scaffold that only aid the ribosome ability to form polypeptides.
Since both prokaryotes and eukaryotes are constantly forming proteins using the amino acids they accumulated through nutrition, therefore, both groups possess ribosome. However, the percentage of rRNA and protein in each group differs. For prokaryotes, the rRNA to protein ratio is close to 2, while in eukaryotes like human is close to one.
Answer: A fluid phospholipid bilayer with embedded proteins.
Explanation: Biological membranes are composed of phospholipids that interact with each other to form a bilayer in which proteins are embedded. Phospholipids have the fatty acyl chains (hydrophobic tails) which face each other to form the interior of the bilayer, while their polar head groups face the outward environment interacting with water molecules. The fluid mosaic model for structure of biological membranes is due to the interactions between the hydrophobic tails of the lipids. The fatty acyl chains of the phospholipids (nonpolar/ hydrophobic tails) in the interior of the membrane form a fluid hydrophobic region while the integral proteins float in the sea of these lipids. The proteins and lipids move freely and laterally in the plane of the bilayer, but movement there is restriction in the movement from one face of the bilayer to the other. The proteins are embedded at regular intervals and are held by hydrophobic interactions between the membrane lipids and the hydrophobic regions of the proteins.
The membrane mosaic is fluid because most of the interactions among its components are noncovalent, thereby leaving the lipid and protein molecules free to move laterally in the plane of the membrane.
Answer:
forced expiration
Explanation:
The speed at which air is expelled from the lungs during the middle portion of a forced expiration is very important to the actions of the internal intercostals.
