KINES 350 Midterm: Exam 2 review notes
Document Summary
H+ pumped across membrane accumulates in between inner and outer membrane, providing a diffusion gradient across the inner membrane that drives. Atp synthesis (2h+ per atp) (a. iii. 4) final h- acceptor is oxygen, forming h2o. Lecture 10 - bioenergetics ii: energy from glucose metabolism. 6 a. i) rq = #co2 produced/#o2 required = 6/6 = 1 a. ii) efficiency = e in atp /e if burned = 32 * 7. 3 / 686 = 34: energy from fatty acid metabolism (palmitate) Lecture 11 exercise metabolism, ergometry and calorimetry. The problem: 60-70% of metabolic energy is lost as heat. How can total energy expenditure be quantified: methods, direct calorimetry total heat liberated by a person is recorded b) Indirect calorimetry (vo2) b. i) o2 utilization and co2 production are recorded as an estimate of tissue use. b. ii) equipment required (b. ii. 1) volume measurement (b. ii. 2) gas analysis b. iii) determination of substrates (b. iii. 1) requires calculation of rer (rq) (b. iii. 1. a) vco2/vo2 (b. iii. 2)
