In neither case does the inhibitor compete with the substrate for the same binding site, so the inhibition cannot be overcome by increasing the substrate concentration.

#Unit 6. System Physiology – Plant

Phytopathogenic bacteria reside within the intercellular spaces of plant organs or in the xylem and many damage plant tissues by secreting toxins, extracellular polysaccharides (EPSs), or cell wall‐degrading enzymes.

#Unit 2. Cellular Organization

The DNA-binding domain occupies residues 1–59. It contains two a-helices separated by a turn. This is a common DNA-binding motif known as the HTH (helix-turn-helix); the two a-helices fit into the major groove of DNA

#Unit 11. Evolution and Behavior

Selfish (cheater) genotypes are expected to increase within populations, a trait that benefits the group would have to evolve by selection among groups, rather than by selection among individual organisms within the groups.

The main physical barriers—the body’s first line of defense—are the epithelial layers of the skin and of the mucosal and glandular tissue surfaces connected to the body’s openings
