Romashka [77]

Explanation:

Neurons are the structural and the functional unit of the nervous system. Two main types of neurons on the basis of their function are sensory neurons and motor neurons.

The motor control in order body occurs in a sequential step. The motor program is selected by the pre motor cortex. This neuron is further stimulated by basal nuclei of the thalamus. This further stimulate the lower motor neuron. This causes the contraction in the skeletal muscle. This information is further move to cerebellum if movement is required.

protons are pumped across the mitochondrial inner membrane as electrons are transferred through the mitochondrial electron trans
Ipatiy [6.2K]

If the facts about proton pumping are true, then protons are pumped into the matrix of the mitochondria.

<h3>What causes the electron transport chain's proton pumping?</h3>

Proton pumps are found in the electron transport chain's complexes I, III, and IV. The complexes absorb the energy generated when electrons migrate energetically downward and use it to pump H +start superscript, plus, end superscript ions out of the matrix and into the intermembrane gap.

<h3>when outside of the Matrix are protons pumped?</h3>

At complexes I, III, and IV, the matrix is pumped of protons (2 per complex). The resultant proton gradient drives ATP synthesis: 2 H+ are generated for every ATP. The inner mitochondrion is charged differently due to the proton gradient.
