What are enzymes and their functions?

Enzymes are proteins that break down molecules.

How do organ systems work together in the body?

Organ systems collaborate to maintain bodily functions.

The respiratory system facilitates gas exchange in the body.

Enzyme activity can be tested by mixing enzymes with substrates.

Food tests like iodine and Benedict's solution help identify nutrients.

Enzymes play a crucial role in digestion by breaking down specific molecules like carbohydrates, proteins, and lipids, with their activity being influenced by factors like temperature and pH.
Understanding the intricate systems of the human body, such as the circulatory system and digestive system, requires knowledge of how cells form tissues and organs, highlighting the interconnected nature of biological processes.

Cells form tissues, which then form organs like the heart and work together in organ systems such as the circulatory system and digestive system.
Enzymes like amylase break down larger molecules into smaller ones in the small intestine, aiding in nutrient absorption.
Enzymes are specific, breaking down certain molecules like carbohydrases for carbohydrates, proteases for proteins, and lipases for lipids.
Enzyme activity increases with temperature until denaturation occurs, affecting the substrate binding.
Practical experiments involve mixing amylase with starch at different temperatures or pH levels to determine optimum conditions for starch breakdown.
Food tests like iodine turning black in the presence of starch help identify nutrients, while Benedict solution and bir's reagent indicate sugars and proteins, respectively.
The respiratory system involves breathing and gas exchange, with oxygen diffusing into the blood in the alveoli and carbon dioxide being exhaled.
The circulatory system, a double circulatory system, involves the heart pumping oxygenated blood to the body and deoxygenated blood to the lungs, with arteries carrying oxygenated blood and veins carrying deoxygenated blood.
