There are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitami
KiRa [710]

Answer:

<u> Essential</u> nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.

You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to <u>micronutrients</u> which you consume in small quantities

<u>Dehydration</u> can develop very quickly when exercising in hot/humid weather conditions.

<u>Proteins</u> are also called 'bodybuilders" due to their function within the body. <u>Amino acids</u> are the building blocks of proteins.

Explanation:

Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body.  They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.  

Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.

Compare and contrast how the normal and mutated proteins adhered to the cell membrane
inn [45]
Normal proteins allow the substances Na + and Cl- to move correctly through the cells of the skin, the pancreas and the lungs.

In contrast, the mutated proteins prevent them from moving through the cell, this causes mucus to accumulate in the skin, in the lungs and the pancreas, a medical condition called cystic fibrosis.

In an animal cell, what is the function of the lysosomes?
Alik [6]
<span><span><span>Release enzymes outside of the cell (exocytosis)</span>
which may serve the purpose of destroying materials around the cell.</span><span><span>Break-down 'digestion' of materials from inside the cell (autophagy)</span> 
i.e. by fusing with vacuoles from inside the cell. 
This could include digesting worn-out organelles so that useful chemicals locked-up in their structures can be re-used by the cell.</span><span><span>Break-down 'digestion' of materials from outside the cell (heterophagy)</span>
i.e. by fusing with vacuoles from outside the cell.
This could include breaking-down material taken-in by phagocytes, which include many types of white blood cells - also known as leucocytes. Specific mechanisms of heterophagy can be:<span><span>phagocytic - by which cells engulf extracellular debris, bacteria or other particles - only occurs in certain specialized cells</span><span>pinocytic - by which cells engulf extracellular fluid</span><span>endocytic - by which cells take-up particles such as molecules that have become attached to the outer-surface of the cell membrane.</span></span></span><span><span>Recycle the products of biochemical reactions that have taken place following materials being brought into the cell by endocytosis (general term for this 'recycling' function: biosynthesis) </span>
Different materials (chemicals) are processed in different ways, e.g. some structures may be processed/degraded within lysosomes and others are taken to the surface of the cell.</span><span>Completely break-down cells that have died (autolysis)</span></span>

In general, the functions of lysosomes involve breaking-down i.e. processing to 'make safe' or make use of, or removing from the cell e.g. by exocytosis, useless and potentially harmful materials such as old worn-out parts of the cell or potential threats such bacteria. Lysosomes can therefore be thought of as the rubbish disposal units within cel
