Raw red alga of the genus Porphyra is part of a traditionalJapanese diet. This alga is rich in porphyran, a polysaccharide that human digestive enzymes cannot break down. Marine bacteria that live on the alga produce a porphyran-digesting enzyme. In Japan, a homologousenzyme is common in one species of intestinal bacteria. Outside of Japan, people have the same species of intestinal bacteria, but they do not have the gene for the porphyran-digesting enzyme. The marine bacteria andthe intestinal bacteria are not close relatives, so they mostlikely did not inherit the enzyme from a shared ancestor.Propose a scenario to explain the observed distributionof the enzyme.
Considering all of the known organisms living on this plant, how many different standard amino acids are known to be used for the ribosomal biosynthesis of proteins in living cells? Select one: O 19 standard amino acids. O 20 standard amino acids. O At least, 21 standard amino acids. O At least, 22 standard amino acids. O Many more than 22 standard amino acids.
In each case, these are enzymes that catalyze thesame reaction in different species. The question is: are they related or not? i.e. Are the structures essentially the same? Often you can get similar reactions from proteins thatevolved from a common ancestor (e.g., trypsin and chymotrypsin). Sometimes the samereaction can be catalyzed by proteins with very different evolutionary origins and with verydifferent structures (e.g., trypsin and subtilisin). Your job is to decide if these proteins have fundamentally different folds or if they have basically the same fold. Briefly justify your answer.1.

Many antibiotics alter the rate of reaction for enzymes that produce and then cross-link the strands of this polymer together. The image below shows the structure of one antibiotic called penicillin as compared to the portion of the peptidoglycan that undergoes cross linkage. Condon A HS.

Why it is important to take the full dosage of antibiotics. Briefly explain 5. Is peptidoglycan still being produced in the portion of the graph marked by the circle in condition B?
Why do cyanobacteria possess heterocysts? View Available Hint(s) for Part A Heterocysts shield the organism's nitrogen fixation enzymes from oxygen. Heterocysts serve as a primitive nucleus in these bacteria. Heterocysts are reproductive structures similar to endospores in other bacteria. Bacterial photosynthetic pigments are located in heterocysts.

Nearly all bacteria contain peptidoglycan. Review the structure of peptidoglycan by selecting the correct characteristics listed below. Check All That Apply Polymer of alternating N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) Contains a tetrapeptide that extends from N-acetylglucosamine (NAG) Contains D-amino acids not found in proteins All bacteria use a peptide interbridge to connect the sugar strands Peptidoglycan is a strong and rigid structure
The death cap mushroom (Amanita phalloides) is considered one of the world’s deadliest mushrooms. The toxicity of the Amanita species is due to the presence of two groups of toxins known as amatoxins and phallotoxins, both made of multiple cyclic peptide chains (circular sequence of bonds). Do some research about the death cap and answer: What makes the Amanita phalloides toxins so harmful that even one cap can kill an adult?
