What is the name of the signaling molecule that triggers a transduction pathway?

• ligand
• GTP
• kinase
• phosphatase

What is the name of the pathway that occurs when a signal is received and then converted into a cellular response?

• signal transduction
• biochemical
• catabolic
• anabolic

What is the name of the secreted molecule that influences nearby cells?

• local regulator
• insulin
• epinephrine

What is the name of the molecule used in signal transduction pathways that readily diffuse and broadcast signals quickly?

• secondary messengers
• ligand
• kinases
• phosphatases

The death signal inactivates ced-9 and triggers programmed cell death.  What is this called?

• apoptosis
• gated ligand channel
• cell communication
• G-protein reception

Phosphorylation cascades involving a series of protein kinases are useful for cellular signal transduction because

• they are species specific

• they always lead to the same cellular response

• they amplify the original signal manyfold

• they counter the harmful effects of phosphatases

• the number of molecules used is small and fixed

What is the name of the molecule that is used in long distance signaling; travels from one gland to another location to trigger the signal?

• hormone
• neurotransmitter
• ion
