Answer:
A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.
Explanation:
A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.
Answer:
The light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.
Most dietary <u>fats </u>are too large to be assimilated and absorbed into the capillaries but they are otherwise absorbed into the lacteals.
<h3>What are dietary fats?</h3>
Dietary fat is necessary for good health. It offers you strength and aids in the absorption of vitamins by your body. Dietary fat has about twice as much energy per gram as carbs and protein.
In the villi ( an organ in the small intestine) is located the lacteal which is a lymphatic capillary that absorbs and assimilates dietary fats.
Most nutrients are also absorbed through the blood capillaries, but as for dietary fats and fat-soluble vitamins, they are absorbed by the lacteals.
