The correct answer is that "the T cell enters a state of anergy".

The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.

Creatine phosphate functions in the muscle cell by ________. creatine phosphate functions in the muscle cell by ________. storin
brilliants [131]
Am certain that Creatine phosphate functions in the muscle by storing energy that will be transferred to ADP to resynthesize ATP. All muscle cells have a little ATP within them that they can use immediately, however, only enough to last for about 3 seconds. Therefore, all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly.
