wariber [46]

Answer: Somatosensory cortex.

Explanation: The somatosensory cortex receives all sensory input from the body. The somatosensory system is a part of the <u>sensory nervous system</u>. These sensory receptor cells are activated by different stimuli such as heat and nociception, giving a functional name to the responding <u>sensory neuron</u>, such as a thermoreceptor which carries information about temperature changes.

3. Large molecules and wastes move<br> through the membrane through
madreJ [45]

Answer: Large molecules and wastes move through the membrane through forms of active transport- endocytosis and exocytosis.

Explanation:

Molecules are moved across the cell membrane via different mechanisms like diffusion, facilitated diffusion and passive transport; however, some very large molecules require specialized types of active transport to cross over- these are endocytosis and exocytosis.

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of <em>invagination;</em> piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle. Different methods of endocytosis such as <em>phagocytosis, pinocytosis </em>and receptor-mediated <em>endocytosis</em>, take in cells,  water and targeted substances respectively.

Like endocytosis, the particles (signal proteins, neurotransmitters and waste material) are surrounded by a phospholipid membrane. However, in exocytosis, this membrane is formed in the cytoplasm, and merges with the plasma membrane’s interior in a process <em>opposite to </em>endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.

Which of the following does the enzyme carbonic anhydrase most likely do to a metabolic reaction?
kumpel [21]

Answer:

The main role of carbonic anhydrase in humans is to catalyze the conversion of carbon dioxide to carbonic acid and back again. However, it can also help with CO2 transport in the blood which in turn helps respiration. It can even function in the formation of hydrochloric acid by the stomach.
