KIN 3515 Exam 1 (100+ Questions) – Bioenergetics, Metabolism, Substrate Use & Calorimetry – Louisiana State University

This document provides over 100 verified multiple-choice and true/false questions with correct answers for KIN 3515: Exercise Physiology at Louisiana State University (LSU), based on the 2025/2026 academic year. It is structured as a complete Exam 1 study and review guide, focused on core physiological mechanisms related to energy production, substrate use, and metabolic responses to exercise. The content reflects actual exam formatting and includes questions on: Carbohydrate vs. fat metabolism, including efficiency, ATP yield, and substrate preference at different exercise intensities Key metabolic enzymes, such as hexokinase, phosphofructokinase (PFK), CPT1, PDH, and their regulatory roles Energy systems: ATP-PCr, fast glycolysis, slow glycolysis, oxidative phosphorylation, and beta-oxidation Hormonal control of fuel mobilization (e.g., epinephrine, cortisol, insulin, growth hormone) Respiratory Quotient (RQ) vs. Respiratory Exchange Ratio (RER), including interpretations, ranges, and practical implications Direct and indirect calorimetry, oxygen consumption (VO2), and calculations of energy expenditure using METs and VO2 data Exercise scenarios that apply energy system transitions over time (e.g., running pace, exercise duration, substrate shifts) Biochemical and physiological terms such as catabolism, potential energy, glycogen storage, and energy efficiency This Q&A guide offers students a strong foundation in understanding how the body produces, transfers, and utilizes energy during rest and exercise. It is ideal for exam prep or as a supplemental review resource. Best for students studying: – Exercise Physiology – Kinesiology – Biological Sciences (with a human metabolism focus) – Health & Fitness Science – Pre-PT, Pre-Med, or Athletic Training programs Keywords: KIN 3515, bioenergetics, metabolism, glycolysis, beta-oxidation, carbohydrate oxidation, fat oxidation, ATP production, PFK, CPT1, PDH, RER, RQ, indirect calorimetry, oxygen consumption, energy systems, hormonal regulation, metabolic enzymes, substrate use, exercise physiology, LSU kinesiology
