|
What 2 enzymes are specific to lysosomes?
|

|
What is a metabolon?
|
A physical association of enzymes for catalyzing sequential steps; sometimes but rarely on the same enzyme even.
|
|
What is substrate channeling?
|
The grouping of metabolic intermediates for sequential steps -> results in a metabolon.
|
|
What is futile cycling?
|
The simultaneous degradation and synthesis of a metabolic intermediate.
|
|
How is futile cycling avoided?
|
By compartmental segregation which sequesters intermediates from cell compartments.
