Why is it important for the body to obtain carbohydrates, fats, and proteins?
- They are mainly for storing excess energy and do not actively participate in metabolic processes.
- They solely contribute to bone density and have little impact on other bodily functions.
- They are the primary source of energy, assist in cell growth and repair, and regulate body processes. (correct)
- They are only needed for muscle development and have no role in energy production.
What is the primary benefit of including a variety of fruits and vegetables in your daily diet?
What is the primary benefit of including a variety of fruits and vegetables in your daily diet?
- Fruits and vegetables primarily offer a high concentration of simple sugars for quick energy.
- They are crucial for boosting fat storage, which acts as a long-term energy reserve for the body.
- The main advantage is their high protein content which supports muscle growth and repair.

How do monosaccharides, disaccharides, and polysaccharides differ from each other?
How do monosaccharides, disaccharides, and polysaccharides differ from each other?
- Monosaccharides are single sugar units, disaccharides consist of two sugar units, and polysaccharides are complex carbohydrates made of many sugar units. (correct)
- They vary in their storage location within the body; monosaccharides are stored in the liver, disaccharides in muscles, and polysaccharides in fat tissues.
- They differ primarily in their physical appearance, with each type having a distinct color and texture.
- The difference lies in their taste profiles; monosaccharides are bitter, disaccharides are sour, and polysaccharides are sweet.

Study Notes
- The body requires carbohydrates for energy, fats for energy storage and insulation, and proteins for building and repair.
- Fruits and vegetable contain essential vitamins, minerals, and fiber which are important for overall health.
- Monosaccharides are simple sugars (e.g., glucose, fructose), disaccharides are two monosaccharides joined (e.g., sucrose, lactose), and polysaccharides are complex carbohydrates made of many sugars (e.g., starch, cellulose).
- Fast carbohydrates are simple sugars that provide quick energy (e.g., white bread, sugary drinks), while slow carbohydrates are complex carbohydrates that provide sustained energy (e.g., whole grains, legumes).
- Saturated fats are solid at room temperature and found in animal products, while unsaturated fats are liquid at room temperature and found in plant-based foods; unsaturated fat is considered the healthier option.
- Proteins are made of amino acids.
- Enzymes are biological catalysts that speed up chemical reactions in the body; produced in cells throughout the body, examples include amylase (in saliva) and pepsin (in the stomach).
- The human digestive system breaks down food into smaller molecules that the body can absorb, starting in the mouth and continuing through the esophagus, stomach, small intestine, and large intestine.
- The body absorbs oxygen from the air through the lungs, where oxygen is transferred to the blood and carried to cells throughout the body.
- The three types of blood cells are red blood cells (transport oxygen), white blood cells (immune defense), and platelets (blood clotting).
- The skin is the body's largest organ, protecting against injury and infection, regulating temperature, and providing sensation.
- Malignant melanoma is a dangerous form of skin cancer; protect from it by avoiding excessive sun exposure, using sunscreen, and wearing protective clothing.
- The skeleton provides support, protects organs, allows movement, stores minerals, and produces blood cells.
- Exercising regularly strengthens bones, increases bone density, and reduces the risk of osteoporosis.
- A herniated disc occurs when the soft cushion between the vertebrae pushes out, often due to injury or age-related wear and tear.
- Voluntary muscles are consciously controlled (e.g., biceps, quadriceps), while involuntary muscles work automatically (e.g., heart, digestive muscles).
- The central nervous system (CNS) consists of the brain and spinal cord which controls and coordinates bodily functions.
- The peripheral nervous system (PNS) includes all the nerves outside the brain and spinal cord, transmitting information between the CNS and the rest of the body.
- Nerve cells (neurons) send signals to each other via electrical and chemical signals across synapses.
- The cerebrum controls thought, memory, and voluntary actions; the corpus callosum connects the two hemispheres of the cerebrum; the cerebellum coordinates movement and balance; the brainstem controls basic life functions such as breathing and heart rate.
- The pituitary gland is located at the base of the brain and releases hormones that control growth and regulate other glands; the thyroid gland, in the neck, releases hormones that regulate metabolism; the pancreas, behind the stomach, releases insulin and glucagon to regulate blood sugar; the adrenal glands, on top of the kidneys, release hormones that regulate stress response and metabolism; the ovaries (in females) and testes (in males) release sex hormones that affect reproduction and development.
- The pancreas produces insulin.
- Diabetes is a metabolic disorder characterized by high blood sugar levels, either because the body does not produce enough insulin or cannot use insulin effectively.
- The liver helps regulate blood sugar levels by storing glucose as glycogen and releasing it when blood sugar is low.
- Smoking is harmful because it damages the lungs, increases the risk of cancer, and contributes to heart disease.
- Exercise is good for the body because it strengthens muscles and bones, improves cardiovascular health, and boosts mood.
- Disadvantages of using doping substances include unfair advantage, health risks (e.g., heart problems, hormonal imbalances), and potential for disqualification,
- Sleeping at least 8 hours per night is important for physical and mental health, allowing the body to repair and regenerate and improving cognitive function.
- Antibiotic resistance occurs when bacteria evolve to become resistant to antibiotics, making infections harder to treat.
- A virus replicates by invading a host cell and using its cellular machinery to produce more virus particles.
- An epidemic is a widespread occurrence of an infectious disease in a community at a particular time, while a pandemic is an epidemic that has spread across multiple countries or continents.
