Question

d) e) f) g) h) i) j) These cell-to-cell junctions allow direct communication between the When all of an enzyme's binding sites are occupied and its rate of work can no longer increase, it is said to have achieved a point of If a cell is making ATP at maximum capacity, creatine kinase will deplete its supply of substrate after approximate seconds (give the range). This is the term for a series of reactions that ultimately releases energy through the breakdown of large biomolecules into smaller monomers. For reversible reactions, this law allows us to predict which reaction rate in will increase if equilibrium is disturbed An enzyme that transfers (or exchanges) a phosphate functional group from one molecule to another is generally called a Study this graph. Briefly describe HOW enzyme activity decreases significantly when its environment becomes acidic or basic? k) What is the term for the point on the graph indicated by the arrow?

Explanation / Answer

e) Saturation - Enzyme saturation is a point at which when the binding sites of all ezymes has been bound by substrate and no further substrate can be bound to it. At this point the rate of reaction does not increase.

f) 4 - 6 seconds - ATP stored in the muscle lasts for approximately 2 seconds and the resynthesis of ATP from creatine phosphate will continue until their storage in the muscles get used up in approximately 4 to 6 seconds. So, a total of 5 - 8 seconds of ATP is available.
