b) What is happening in the cells, tissues, and body? what is the basic problem? Relate this concept to a disease.

Answer 1

Ans)a) Metabolism refers to all of the chemical reactions that take place within an organism by which complex molecules are broken down to produce energy and by which energy is used to build up complex molecules.

- Medications, hormones, diet and exercise can all affect metabolism. It is related to weight because it influences the amount of energy, the body needs at any given point.

- Metabolicdiseases are most commonly the result of malfunctioning proteins or enzymes that are critical to one or more metabolic pathways. Protein or enzyme malfunction can be the consequence of a genetic alteration or mutation. However, normally functioning proteins and enzymes can also have deleterious effects if their availability is not appropriately matched with metabolic need.

b) Cells are considered the fundamental units of life. The cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task.

- At each level of organization—cells,tissues, organs, and organ systems—structure is closely related to function.
