**Membrane Proteins and Carbohydrate Attachment in Animal Cells**Membrane proteins of animal cells often have the majority of their polypeptide chains extending above the plasma membrane surface. Carbohydrate molecules covalently attached to the polypeptides maintain the amino acid chains in an extended configuration. These membrane proteins are typically classified as:a) Lipoproteins b) Extracellular proteoglycans c) Glycoproteins d) Peptidoglycans e) β-barrel proteins Carbohydrates can also be attached to polypeptide chains through serine, threonine, or hydroxylysine amino acid residues. These specific types of carbohydrates are known as:a) Glycosaminoglycans b) O-linked oligosaccharides c) Lipopolysaccharides d) O-antigens e) N-linked oligosaccharides

Biomolecules are organic molecules that take part in various biochemical reactions. These are mainly…

Protein modifications that involve disulfide bonds occur in the following;(there may be more than one answer) golgi endoplasmic reticulum ) chloroplast (plastids) peroxisome mitochondria
At what level of protein structure (primary, secondary, tertiary, or quaternary) will protein structure be initially altered? Heating a protein (due to fever), causing hydrogen bonds to break. Drastic changes in pH (like the above patients), causing some polar amino acids to turn into non-polar amino acids
Please, help with the answer and explain it: When observing a bacterial cell, a scientist observed a chain forming attached to a ribosome. The chain absorbed a stain that was specific for amino acids, The chain that was forming was completely linear, representing which level of protein structure? protein? A) primary B) secondary C) tertiary D) quaternary
A molecule of glycogen is formed by linking glucose molecules through this process. The separation of polymers into smaller units makes use of this process. This process does not involve breaking peptide bonds, but it does involve unfolding protein structure. The addition of water to break proteins into amino acids is an example of this process. Dehydration Synthesis Using acids to cook raw fish is an example of this process. This process removes water to link two or more amino acids. Denaturation Breaking DNA into nucleotides involves this process. The change to the color and consistency of an egg during cooking is an example of this process. Monomers are linked together through this process. Hydrolysis
Which type of protein is classified by a polypeptide which is arranged in long strands or sheets? fibrous proteins globular proteins membrane proteins intrinsically disordered proteins
Which statement most accurately characterizes the effect of high temperatures (above 37 celsius) on protein folding? High temperature increases the rate of protein folding, so proteins adopt their native fold faster. There is no effect of high temperature on protein folding. Proteins are denatured, then re-fold into their native state upon cooling. Proteins are denatured, and at risk of forming intermolecular aggregates.
Molecules which do not require channel proteins to move across a cell membrane____________ are lipid soluble are lipid insoluble are hydrophilic must always be moved from a point of low concentration to high concentration
