Respiration. The process by which energy is released from food molecules into a form more easily used by the cell when combined with oxygen.
What is the original source of energy for respiration? Glucose.
Where does the energy made from glucose go? It is stored in the chemical bonds of ATP.
Word formula for respiration. Glucose + oxygen ---------------> carbon dioxide + water + energy
How many molecules of ATP are produced? 36.
What are the raw materials of respiration? Glucose and oxygen.
ATP. Stands for adenosine triphosphate, an organic compound that stores respiratory energy in the form of chemical bond energy for transport from one part of the cell to the next.
ADP. Stands for adenosine diphoshate, one phosphate is removed from ATP.
Formula for the hydrolysis of ATP. Water +ATP ------------> (with help of ATPase) ADP + P+ Energy.
Where does respiration take place? Mitochondria.
Organisms that cannot produce their own food and must obtain their nutrients from outside sources. Heterotrophs.
Organisms that can make their own food from taking in inorganic molecules (water, sunlight, carbon dioxide) and make organic compounds, such as glucose. Autotrophs.
True or False: Respiration is a continuous process that doesn't stop. True.
True or False: Aerobic respiration needs oxygen. True.
Aerobic respiration. Process by which glucose is completely oxidized (broken down by oxygen) into carbon dioxide and water.
Aerobic respiration equation. Glucose + Oxygen ----------------> (with help of enzymes) water + carbon dioxide + ATP.
Where does anaerobic respiration occur? Cytoplasm.
Anaerobic respiration/Fermentation. Respiration that can occur without oxygen.
Two types of anaerobic respiration. Alcoholic fermentation and lactic acid fermentation.
What type of organisms go through alcoholic fermentation? Yeast.
What types of organisms go through lactic acid fermentation? Bacteria and humans during muscle fatigue.
True or False: The first step to both aerobic and anaerobic respiration is glycolysis. True.
Anaerobic respiration formula. Glucose + 2 ATP -----------------> 2 pyruvic acids + ATP.
Formula for alcoholic fermentation. Glucose ------------------> (with help of enzymes) 2 ethyl alcohol + 2 carbon dioxide + 2 ATP
True or False: Anaerobic respiration is more efficient than aerobic. False, aerobic is more efficient than anaerobic.
What causes dough to rise during alcoholic fermentation? 2 Carbon dioxide.
What is the end product of lactic acid fermentation? Lactic acid.
What is the waste product of lactic acid fermentation? Lactic acid.
During which phase of aerobic respiration is the most ATP produced? Electron transport chain.
Where does the energy end up? Inside the bonds of ATP.
Why is respiration significant? It produces ATP, which is essential for metabolic processes.
