Practise MYP Biology questions on 4.1 Nutrition and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Which of the following best describes the functional importance of 'materials' obtained through nutrition, as distinct from energy?
In the context of the body’s internal transport systems, how do the roles of water and iron compare?
How do the specific environmental conditions of a habitat, such as an arid desert or a cold arctic region, influence an organism's nutritional adaptations?
Which of the following describes the correct sequence of events that allows energy from a carbohydrate to be used by a cell?
True or False: An essential nutrient is a substance that the body requires but cannot produce on its own, meaning it must be obtained through the diet.
They serve as the primary source of immediate fuel for movement
They are converted directly into glucose for cellular respiration
They provide the molecules necessary to build and repair body structures
They are required to catalyze all metabolic reactions
Water provides the chemical energy required for transport, while iron acts as a catalyst to build enzymes.
Water is used primarily for insulation and protection, while iron acts as the main medium for chemical reactions.
Water is a structural material used to build cell membranes, while iron is used to store extra glucose as glycogen.
Water acts as a medium for the transport of substances, whereas iron is a specific requirement for the transport of oxygen.
They eliminate the need for essential nutrients
They change the chemical process by which glucose is used in respiration
They prevent the body from using fat for energy storage
They dictate the specific minerals and insulation strategies required for survival
Digestion into glucose, transport via blood, release via respiration
Digestion into vitamins, storage as minerals, release via respiration
Absorption as fat, conversion to glucose, release via respiration
Respiration, storage as glycogen, transport via blood
True
False
