Should I perform a PCA on my datas?

Hi, I'm new to the statistic world.
I have doubts about pca. I am performing the statistics of my study and I have a lot of data. I wonder if I can perform a pca on these data if so, how should I organize this data?
I have the enzymatic activity of different enzymes for each individual(n=10); however, my data of bioaccumulation were performed in a "pool" of six organisms.
I know it can be a little bit stupid but can someone help me?
