Which breakdown produ...

carboxyl group - correct answer A -COOH group, found in organic acids. amino group - correct answer a chemical group consisting of a nitrogen atom bonded to two hydrogen atoms Where are the hydrophobic amino acids found in the protein? - correct answer found in the interior of the protein What kind of bond connects a positively charged group and a negatively charged group? - correct answer ionic bond What type of reaction forms a peptide bond? - correct answer dehydration synthesis What...

The LEP gene codes for an anorexigenic hormone. Interestingly, breastfeeding has been shown to alter methylation of the promoter of this gene, leading to increased LEP expression. What is likely happening in response to breastfeeding? - correct answer Breastfeeding decreases the methylation of the promoter of the LEP gene, increasing the spacing between nucleosomes. A patient with xeroderma pigmentosum is prone to developing multiple skin cancers starting in childhood. This occurs because ...

Hydrogen bond - correct answer Weak bond interaction Between two molecules amino group - correct answer Consists of hydorgen and nitrogen atoms (-NH3+) macromolecules - correct answer A giant molecule in a living organism formed by the joining of smaller molecules: a protein, carbohydrate, or nucleic acid. polymer - correct answer a long molecule consisting of many similar or identical building blocks linked by covalent bonds Amino acid - correct answer Amino group + Carboxylic acid + R gr...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - correct answer Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the develo...
