The role of enzymes in a chemical reaction is to : Lower the activation energy while increasing the rate of reaction
The graph shown on the left is an uncatalyzed chemical reaction while the graph on the right is a catalyzed chemical reaction.
Catalyzed chemical reactions have lower activation energy and a faster rate of reaction while uncatalyzed chemical reaction has a higher activation energy and a slower reaction rate. because catalyst increases the rate of a chemical reaction by lowering its activation energy.
Hence we can conclude that The role of enzymes in a chemical reaction is to : Lower the activation energy while increasing the rate of reaction

Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.
1. Number of postsynaptic neurons
In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.
2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.
3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.
4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.
Answer:
pollen is important in fertilization because pollen carries male gamete and it helps in transportation of male gamete during fertilization in mainly gymnosperms and angiosperms.
