Explanation

Vitamin A is essential for the production of rhodopsin, the visual pigment in the retina that allows us to see in low light conditions.

Explanation

• Animals that migrate long distances need a compact and energy-dense source of fuel to sustain them during their journey.
• Fat is the most energy-dense nutrient, providing approximately 9 kcal/g, compared to carbohydrates (4 kcal/g) and protein (4 kcal/g).

Explanation

Kwashiorkor is a condition caused by a deficiency of dietary protein, leading to an imbalance in the gastro-intestinal system. It is characterized by:

• Edema (swelling) in the legs, feet, and face
• Diarrhea
• Weight loss
• Hair loss
• Skin lesions
• Impaired immune function

Explanation

• The period of rapid growth and development is called adolescence.
• This stage typically involves significant physical, emotional, and cognitive changes as individuals transition from childhood to adulthood.

Explanation

• The Fats is Lipid or Fatty acid, not Starch.
• Starch is a type of carbohydrate.

Explanation

• Glycolysis, the splitting of glucose, releases a small amount of energy that is enough to generate 2 ATP (adenosine triphosphate) molecules.
• This process occurs in the cytosol of cells and is the first step in cellular respiration.

Explanation

• Photolysis is the process by which water (H2O) is split into hydrogen ions (H+), electrons, and oxygen (O2) in the presence of light.
• This process occurs in the thylakoid membranes of chloroplasts during photosynthesis and is driven by light energy.

Explanation

• The dark reaction, also known as the Calvin cycle.
• It is a light-independent reaction that occurs in the stroma of the chloroplast.
• This process uses the energy from ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.

Explanation

• The light-dependent reactions (also known as the Hill reaction) occur in the thylakoid membranes of the chloroplast.
• Thylakoids are specialized membranous structures found in chloroplasts, where light energy is absorbed and converted into ATP and NADPH.

Explanation

The fundamental molecule produced during photosynthesis is glucose

Key Product: Glucose (sugar/carbohydrate) is the main energy-storing molecule.

Purpose: It is used for plant respiration and as a building block for cellulose.

By-product: Oxygen is also produced and released into the atmosphere
