The glucose-alanine cycle is a method of transferring ammonia from the skeletal muscle to the liver. In this process the non-toxic carrier of ammonia is which of the following compounds? Alanine Which of the following enzymes is correctly paired with its activator? N-acetylglutamate synthat...

How do most enzymes reduce the activation energy needed to move a reaction forward? Providing an active site most complementary the transition state We have an expert-written solution to this problem! An enzyme has a mutation within the substrate binding of the coenzyme needed for covalent ...

what percentage of water is in the body? 60% Relationship between protons and acids & bases Acids donate proton. Bases accept proton Strong Acids Vs Weak Acids Strong acids fully dissociate (100%) and weak acids partially dissociate properties of water dipole dipole polar ...

Which of the following proteins is likely to have quaternary structure? A multimeric protein that contains multiple peptide chains Prosthetic groups are complex nonprotein molecules that participate in catalysis by providing functional groups that form a covalent intermediate between the enz...

Which of the following lipoproteins distributes dietary lipids? chylomicron The interaction of chylomicrons with lipoprotein lipase is stimulated by which of the following Apo proteins? ApoC II Nascent chylomicrons are synthesized in which tissue? Intestine Bile salts are syn...

Cortisol is a steroid hormone that increases protein catabolism from skeletal muscle. It does this through which of the following mechanisms? Transcriptional regulation Pyruvate dehydrogenase complex is highly regulated. The enzyme will be most active when which of the following compounds is...

Ribose and NADPH A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemo...

What enzyme is used by the gluconeogenic pathway but NOT in the glycolytic pathway? Phosphoenolpyruvate Carboxykinase PEPCK Newborn screening results show a biotinidase deficiency in a 2 day old infant. The deficiency impairs the infant's ability to reuse and recycle biotin. Due to the enzy...

3, 2, 4, 1 Order the following statements to illustrate the correct cascade of events that occurs after ligand binding of G-protein coupled receptor (heptahelical receptor). 1. Degradation of cAMP by phosphodiesterase 2. Dissociation of Gβ and Gγ subunits 3. G protein exchanges GDP for G...

Folding of the secondary structures A 19-year-old male is diagnosed with Creutzfeldt-Jakob Disease, which is caused by the introduction of an amyloid fold in the disease-causing protein. The introduction of this fold causes the protein to transition from a primarily α-helical structure to an aggre...

The cellular uptake of LDL increase intracellular cholesterol levels. This has which of the following impacts on de novo cholesterol synthesis? Increases degradation of HMG-CoA reductase Dietary cholesterol is primarily transported in the body by which of the following lipoproteins? Chylomi...
