Please select ALL of the statements that are true of Bt endotoxin: It is isolated from the bacteria, Bacillus thuringiensis. It is a non-specifically acting protein meaning it will affect any organism that consumes it. Bt begins to function within minutes by affecting the gut of the caterpillar, enzymes break down the gut allowing for bacteria to enter the hemolymph (caterpillar bloodstream equivalent). Like Leptodoptera, wasps and bees are also affected by Bt toxin. Bt toxin is used on Leptodoptera because the insects damage the plants by boring into the roots. Using Bt endotoxin genes in plants, we can prevent the use of some insecticides.

Decide whether each of these statements is true or false, and then explain why: 1) Any particle that is bound to the surface of a phagocyte will be ingested by phagocytosis. 2) Like the LDL receptor, most of the more than 25 different receptors known to participate in receptor-mediated endocytosis enter coated pits only after they have bound their specific ligands. 3) Late endosomes are converted to mature lysosomes by the loss of distinct endosomal membrane proteins and a further decrease in their internal pH.
