TEST BANK FOR ESSENTIAL CELL BIOLOGY 5TH EDITION BY BRUCE ALBERTS, ALEXANDER D JOHNSON, DAVID MORGAN, MARTIN RAFF, KEITH ROBERTS, PETER WALTER ISBN 9780393691092 Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be described as the smallest liv...

2 ways phosphate addition/removal causes conformational changes - Answer 1)Phosphorylation has a lot of negative charges that interfere with interactions between substrates --> forces protein into different conformations 2) phosphorylation of an enzyme can also alter substrate-binding affinity via electrostatic repulsion what happens to the GPCR and g-protein when a hormone reaches the GPCR receptor on cell membrane? - Answer hormone triggers a conformational change in receptor, which s...
