Background information: You have discovered a protein that is
capable of defending agricultural crops from a variety of insects
known to negatively impact agriculture, while not creating
resistance, not being harmful to non-target species, and exhibiting
no negative environmental consequences.

How do neurons conduct information? (Please note: this question refers only to events occurring during the time from the receipt of an external signal by a single neuron to the time this information is relayed to the next neuron or muscle. It does not include anything relating to the initial sensory neuron that stimulated the neuron in question, or the subsequent neuron or muscle that this neuron stimulates.) a. What kind of protein “senses” incoming information at the post-synaptic membrane?...

PART A
Correctly order the steps 1-8 as they occur during the transport
of glucose via the phosphotransferase system (PTS):
HPr donates the phosphate group to enzyme IIA (EIIA);
phosphoenolpyruvate is produced as an intermediate of glycolysis;
EI donates the phosphate group to a histidine-rich protein (HPr);
as it enters the cell glucose is phosphorylated by EIIB;
phosphoenolpyruvate donates its high-energy phosphate group to
enzyme I (EI); EIIA passes its phosphate group to Enzyme IIB
(EIIB); glucose is transported across...

Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...

32. Study the signaling pathway illustrated below, which involves two different receptors. Assume that a protein is active only when it is activated, but not inhibited, by its upstream signaling molecules. Activation and inhibition are indicated by normal and blunt arrows, respectively. Assume that the transcription regulator can be activated by either the binding protein or the kinase that are immediately upstream of the transcription factor. Under which of the following conditions will the expression of target:gene "X" be induced?...
