Gymnosperms and angiosperms are both vascular, seed-bearing plants. However, gymnosperms release their seeds in cones (like pinecones) while angiosperms release their seeds through flowers.
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
