Answer:
The mechanism by which cells regulate their ability to respond to extracellular messengers is known as receptor signalling.
Explanation:
Cells senses an environment and communicate which each other through ligand-induced activation of signalling receptors at the cell surface. Signalling receptors enter the endocytic pathway and are sorts into various compartments. Endocytosis regulates cell signalling by controlling the number of receptors available for activation in plasma membrane and activation of receptors or downstream effectors often stimulate receptor endocytosis.
The monosaccharides important in food and health are glucose<span> (sometimes called dextrose), </span>fructose<span>, and </span>galactose. The disaccharides are sucrose (glucose<span> +</span>fructose), lactose (glucose<span> + </span>galactose), and maltose (glucose<span> + </span>glucose<span>).</span>
Answer:
The composition of a planet's atmosphere also influences its temperature, particularly the concentration of greenhouse gases present. The Earth converts solar radiation in the visible spectrum to infrared radiation, which it emits; greenhouse gases absorb infrared radiation and warm the atmosphere.
Explanation:
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
