Why amino acid called alpha amino acid?
The variable R group of each amino acid is attached to the carbon alpha to, or immediately adjacent to, the carbon bearing the carboxylic acid functionality.
Describe the exchange of substances across the capillary cell membrane?
Capillary exchange... You have a higher blood pressure and a lower osmotic pressure at the arteriole end of the capillary, this causes water to leave the capillary. The gases oxygen and carbon dioxide and nutrients like glucose and amino acids follow their concentration gradients and diffuse across the capillary membrane. At the venule end of a capillary your blood pressure is less than that of osmotic pressure and water returns to the capillary.Hope this helped. I'm Looking for diagrams of this same thing. Any ideas?Here is a website I found that might help out too.http://www.mhhe.com/biosci/esp/2002_general/Esp/folder_structure/tr/m3/s10/trm3s10_2.htm
What of the following brings amino acids into a ribosomes to be assembled into a protein?
It's called a Peptite bond, I believe. A peptite bond is formed between adjacent amino acids. :)
What happens after blood enters the glomerulus in the kidney?
The glomerulus is the cluster of capillaries that branch off the renal artery in the kidneys. It is here that filtrationtakes place - small molecules such as glucose, water, ions and amino acids diffuse through the narrow capillary walls and into the nephron.
Are amino acid absorbed into the blood?
In the gut, amino acids are absorbed from the small intestine into the blood by active transport. However, if you are referring to amino acids being reabsorbed in the kidney from the nephron back to the blood, then that is incorrect - amino acids aren't reabsorbed at all, because they weren't filtered in the first place. This is due to the protein molecules being too large to diffuse across the Bowman's Capsule.
Amino acids tend to diffuse from blood capillary to adjacent cell because?
Because cells need the amino acids to produce proteins.
What is a beta-amino acid?
A beta-amino acid is an amino acid which has the amino and carboxylic functional groups attached to adjacent carbon atoms.
How does amino acids get to the site of protein synthesis?
Amino acids are attached to transfer RNA to form an aminoacyl-tRNA and diffuse to the ribosome, which is the site of protein synthesis.
What Bond forms between adjacent amino acids during a condensation reaction?
The bond which forms between adjacent amino acids during a condensation reaction is called a peptide bond.
What enzymes recognizes proteins and cleave the bonds between adjacent amino acids?
Proteases
Which molecule can diffuse from the digestive tract into the human bloddstream without first being digested?
amino acid
Would amino acids diffuse through the membranes?
No because all amino acids are polar. RCH(NH2)COOH as the COOH part disassociates and polar compounds can not passively pass through a cell membrane. There are carrier proteins that negotiate that passage.
Why amino acid called alpha amino acid?
The variable R group of each amino acid is attached to the carbon alpha to, or immediately adjacent to, the carbon bearing the carboxylic acid functionality.
The chemical bond adjacent amino acids is called an?
Adjacent amino acids in a protein are held together by peptide bonds.

What are 2 substances that diffuse freely across a cell membrane?
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.

It's called a Peptite bond, I believe. A peptite bond is formed between adjacent amino acids. :)
