<span>The importance of the fat deposits and the surrounding fascia to kidneys is that they have a protective function. There is two layers of fat around kidney: the pararenal fat which is superficial to the fascia and the perirenal fat, or adipose capsule of the kidney which is below the fascia and superficial to the renal capsule. Adipose tissue acts as protective padding which means it protects kidneys from external force and from moving around in the abdominal cavity.</span>

Answer:
The receptors on the postsynaptic membrane (dendrites) of a neuron receive(s) the transmitter released by other neurons.
Explanation:
Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites and an axon. The <u>dendrites </u>are cytoplasmic extensions that <u>receive stimuli from other cells</u>. The axon is a long formation capable of conducting the electrochemical signals.
Every neuron forms connections with other neurons. These connections are known as synapsis. As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area of the other neuron and binds to its <u>receptors in the postsynaptic membrane,</u> located in dendrites of the other neuron. This receptor is a protein structure that triggers an answer. The binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space.
Enzymes speed up all of the reactions that happen inside cells. They help with digestion and our metabolism. Enzymes can do a few different things like:
Break up big molecules into smaller pieces, so they can be absorbed more easily by the body.
Enzymes also are very picky catalysts, and will only “speed up” certain types of reactions.
Hope this helps you!! (:
Organelles exist within cells, which exist within tissues. Communities exist within ecosystems, which exist in the biosphere.
