Cellular Respiration [IB Biology SL/HL]

This Key Concept video explores how ATP functions as the cell's energy currency and the process of cellular respiration that regenerates it. It explains the interconversion of ATP and ADP, examines different respiratory substrates, and discusses factors that affect the rate of respiration, including temperature, pH, and substrate concentration. The video concludes with an overview of how respirometers are used to measure respiration rates. 0:00 Introduction 0:25 ATP 1:25 Cellular respiration 3:20 Interconversion of ATP and ADP 4:09 Respiratory substrates 4:50 Factors affecting rate of respiration 5:30 Limiting factors - temperature 6:53 Limiting factors - pH 8:05 Limiting factors - substrate concentration 9:39 Respirometers More IB Biology Videos & Exam Questions can be found at: Revision Village - IB Biology https://www.revisionvillage.com
