Nutritional Biochemistry Exam
Questions
Course Introduction
Nutritional Biochemistry explores the molecular and chemical processes that underlie the relationship between nutrients and human health. The course delves into the digestion, absorption, transport, and metabolism of carbohydrates, proteins, lipids, vitamins, and minerals, emphasizing how these nutrients interact at the cellular and systemic level. Students will examine the biochemical pathways regulating energy production, nutrient utilization, and the role of enzymes, hormones, and genetic factors in metabolism. By understanding the biochemistry of nutrition, students gain insights into disease prevention, dietary requirements, and the impact of nutrition on overall health and wellness.
