Q. Q. 10/24 * Answer the Background Questions on your INVESTIGATING MUSCLE FATIGUE Worksheet (1)What is cellular respiration and what is the cellular respiration equation? (1)Differentiate between anaerobic respiration and aerobic respiration. What are two aerobic processes involved in cellular respiration?

Cellular Respiration

Chemical Energy and Food • Organisms get the energy they need from food. https: //app. schooltube. com/video/6760 f 71 e 291 14658 bc 6 a/Cellular_Respiration http: //www. youtube. com/watch? v=h. JFy. Sk. Ai-ZA

Overview of Cellular Respiration Intro Video • Cellular Respiration: is the process that releases energy (ATP) from food in the presence of oxygen. • Cell Respiration Reaction:

Oxygen and the Energy Chain • Pathways of cell respiration that require oxygen are called AEROBIC • Pathways of cell respiration that DO NOT require oxygen are called ANAEROBIC

Comparing Photosynthesis and Cell Respiration • Photosynthesis removes carbon dioxide from atmosphere and cell respiration puts it back. • Photosynthesis releases oxygen into the atmosphere and cell respiration uses that oxygen to release energy from that food.

The process of Cell Respiration Stages 1. Glycolysis 2. Kreb’s Cycle 3. Electron Transport Chain

The 3 stages of CR Stage #1 Stage #3 Stage #2

Stage 1 - Glycolysis • Glycolysis means ‘sugar breaking’ – Glyco=sugar – Lysis= break (lyse) • Takes place in the cytoplasm of cell • Is an ANAEROBIC process – doesn’t require oxygen

Stage 2 – Kreb’s Cycle • In the presence of oxygen, pyruvic acid produced in glycolysis passes to the Kreb’s Cycle. • Takes place in mitochondria • Is an AEROBIC process –requires oxygen

Stage 3 – Electron Transport Chain • Takes place in the mitochondria • Is an AEROBIC process –requires oxygen
