You are studying the enzyme protease in germinating seeds. you find that protease activity increases tenfold after treatment of the seeds with a hormone, gibberellic acid. how would you show that this increase is due to:
a. release of a transitional repressor by the hormone?
b. allosteric inhibition of a transcriptional repressor by the hormone?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 8 options: the cold balloon expands and rises. the warm balloon shrinks and sinks. the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the warm balloon expands and rises. the cold balloon shrinks and sinks.

Omg substrates with the same size and shape as the active site will bind to the enzyme. why is the key labeled the “bad” substrate?
