The correct answer is option Energy is lost at each trophic level.
In a Ecological pyramid, the energy is transferred from the producer to the consumer level. The ecological pyramid is triangular in structure, this is because the number of organism on each successive trophic level is less than the preceding one or the one below it.
The reason of this shape of ecological pyramid is on subsequent trophic level, the amount of energy transferred is only 10%. The rest of the energy is dissipated in the environment in the form of heat. As only 10% of total energy is transferred to the subsequent level, The amount of energy reaching to tertiary consumer is very less that it cannot meet the energy demand of next level.
The production will most likely be halted by an inhibitor until the cell needs more to be produced
The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
The <u>vesicles</u> pick up whole and partial neurotransmitters from the synaptic gap and bring them into the terminal button, where other structures recycle these neurotransmitters for future use.
Within the presynaptic terminals is where the synthesis of the small-molecule neurotransmitters takes place. A process known as slow axonal transport is responsible for moving enzymes from the neuronal cell body to the cytoplasm of nerve terminals at a rate of 0.5–5 millimetres each day. These enzymes are necessary for the production of transmitters and are produced in the neuronal cell body. Transporter proteins, which are typically located in the plasma membrane of the nerve terminal, are the ones responsible for bringing the precursor chemicals that these synthetic enzymes use into the terminal. Enzymes produce a neurotransmitter pool in the cytoplasm, which must then be loaded into synaptic vesicles using transport proteins in the vesicular membrane. Within the synaptic vesicles, the final synthetic steps of the production of certain small-molecule neurotransmitters are actually carried out.
