What is the roles of enzyme activator? Describe the structure of the mitochondria and explain how this structure allows for this increase in efficiency, including details on the relationship between the important steps of cellular respirat Are proteins made in the cytoplasm or the ribosomes?
The catabolite activator protein (CAP) is expressed and forms a complex with cyclic adenosine monophosphate (cAMP). cAMP is a molecule that is present in high concentrations when glucose levels are low. This double requirement prevents the lac operon from being expressed when an easier to metaboliz...

An RNA polymerase II activator often contains several regions that contribute to its potency, an organization ostensibly analogous to the modular architect... T Chi,M Carey - 《Mol.cell.biol》 被引量: 91发表: 1993年 Structural Mechanisms Underlying Posttranslational Modification by Ubiquitin-Like P...
gondii because it can directly subvert the signal transducer and activator of the transcription 3/6 (STAT3/6) signal and target the host cell nucleus22. ROP16-based DNA vaccines can significantly enhance cytokine IFN-γ, IL-2, and IL-4 production for acute infections and increase survival by...
NCLs are considered lysosomal storage diseases (LSD) characterized by a heterogeneous origin of the storage material. This material consists mostly of accumulation of ceroid-lipopigments, subunit c of mitochondrial ATP synthase or sphingolipid activator proteins A and D in lysosomes. Commonly, the accum...
proteins on the captured cell. If a cell triggers more of the NK cell's activator receptors, the killing mechanism will be turned on. If the cell triggers more inhibitor receptors, the NK cell will identify it as normal and leave the cell alone. NK cells contain granules with chemicals ...
Note that in the Cdc2 activation module (Figure 1a), active Cdc2–cyclin B activates its activator Cdc25 and inactivates its inhibitor Wee1. This double positive feedback can be shown to result in an all or none activation that will not flicker on and off once it is turned on, if ...
What are the two types of sweat glands? How does active transport help to maintain concentration gradients? a. What are the three types of capillaries? b. What kind of functions would each type be used for? What two pathways may be used to produce prothrombin activator? Which is faster?
activator inhibition c. diffusional regulation d. enzyme activation How do enzymes catalyze reactions? a) Enzymes bind with and change the conformation of substrates. b) Enzymes carry out a reaction without needing reactants. c) Enzyme...
