**Question:**Skeletal muscle myosin heavy chain is a mechanoenzyme that requires ATP for its function. Other enzymes, such as phosphofructokinase-2, also rely on ATP. How are PFK-2 and myosin II different in their use of ATP?**Options:**- Both enzymes use ATP in the exact same way.- PFK-2 functions as a kinase, whereas myosin functions as a phosphatase.- PFK-2 catalyzes ATP hydrolysis, whereas myosin does not.- Myosin catalyzes ATP hydrolysis, whereas PFK-2 does not.- PFK-2 binds to ATP or ADP + Pi, whereas myosin undergoes covalent modification via phosphorylation.**Submit Button:**Below the options, there is a "Submit" button to finalize your selection.

Figure 37.5 Heat shock proteins (HSP) are so named because they help refold misfolded proteins. In response to increased temperature (a “heat shock"), heat shock proteins are activated by release from the NR/HSP complex. At the same time, transcription of HSP genes is activated. Why do you think the cell responds to a heat shock by increasing the activity of proteins that help refold misfolded proteins?

THOUGHT QUESTION Imagine we identify a gene that is directly responsible for the effects of vasopressin on male mammals, including humans-we will call it trust1-that leads to the production of a vasopressin receptor in the brain, which we will call TRUST1. There are different versions of trust1, all of which lead to different levels of the behavior associated with this neuropeptide on male behavior. Give some examples where it would be a good idea to know a particular males genotype-that is, which of the trust1 genes he has. Give an example of when you think science has gone too far and this information should not be known.
