Nutrition
Biology · 50 practice questions
Modes of nutrition — autotrophic and heterotrophic; plant nutrition (photosynthesis, chemosynthesis, mineral requirements); animal nutrition — classes of food substances, food tests, the mammalian tooth (structure, types, functions), the alimentary canal and the nutrition process (ingestion, digestion, absorption, assimilation).
- Compare autotrophic and heterotrophic nutrition, and differentiate holozoic, parasitic, saprophytic and carnivorous-plant feeding.
- Differentiate light/dark reactions of photosynthesis and the necessity of light, carbon(IV) oxide and chlorophyll.
- Identify macro/micro-nutrients and their deficiency symptoms.
- Relate the importance and deficiency diseases (e.g. scurvy, rickets, kwashiorkor) of each food class.
- Describe the mammalian tooth and alimentary canal (including liver, pancreas, gall bladder) and relate their structures to digestive functions.
Try a few questions
- Practice question 1
Water, although it provides no energy, specifically is still considered an essential component of a balanced diet mainly because it
- A.is entirely optional and can be safely excluded from any diet indefinitely
- B.is required for numerous essential processes within the body
- C.a factor entirely unrelated to being required for essential bodily processes
- D.is classified as a food class identical to carbohydrates or protein
Show the answer
B. is required for numerous essential processes within the body
Water, although providing no energy, specifically is still an essential part of a balanced diet because it supports essential body processes.
- Practice question 2
The pancreas, a gland associated with the mammalian digestive system, specifically produces
- A.digestive enzymes that act within the small intestine
- B.saliva, a substance that is instead produced by the salivary glands
- C.a factor entirely unrelated to the production of digestive enzymes
- D.bile, a substance that is instead produced mainly by the liver
Show the answer
A. digestive enzymes that act within the small intestine
The pancreas, associated with the digestive system, specifically produces digestive enzymes that act in the small intestine.
- Practice question 3
The stomach, part of the mammalian alimentary canal, specifically functions mainly to
- A.churn food and begin the chemical digestion of proteins
- B.produce bile, a substance instead produced by the liver
- C.absorb the majority of digested nutrients into the bloodstream
- D.a factor entirely unrelated to churning food or digesting protein
Show the answer
A. churn food and begin the chemical digestion of proteins
The stomach specifically functions mainly to churn food and begin the chemical digestion of proteins.
