Unformatted text preview: phosphate groups converting it to cAMP Signal relayed in signal transduction pathway can trigger an increase in calcium in the cytosol Inositol triphosphate (IP3) and diacylglycerol (DAG) act as second messengers A signal (and the response) is amplified Can cause different responses with the same signal molecule Same signal for cells can have different effects in cells with different proteins and pathways Energy is the capacity to cause change. Some forms of energy can be used to perform work. Contains various forms including potential (includes chemical energy) and kinetic (includes heat energy; does not have the potential to perform work) Energy is transformed, not created or destroyed...
