ATP is the last stop in catabolism Binding cofactos if a protein can’t do everything, coenzymes—vitamins, multiple active sites in enzymes are connected by tunnels, speeding up entire metabolic pathways ATP-binding cassette(ABC transporters)-uses ATP hydrolysis to pump substrates into or out of the cell, hydrophobic molecules from cytoplasm to outside of the cell, imp. In resistance of tumor cells in drugs Binding sites non-covalent Anchors hold covalent bonds to protein Psi bond rotates around a C-C bond where the 1 st C is alpha carbon and the second is the C of the C=O group Phi rotates around the N of the alpha amino group and the alpha C atom IF BOTH PHI AND PSI ARE NEGATIVE ITS AN ALPHA HELIX Phi and Psi bonds restricted due to physical interference between the O of the peptide C=O group of one amino acid and a H atom attached tot the alpha amino group of a second AA H-bonds are internal in alpha helix and how chains are attached together with a polypeptide background

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
