Biology 4.2.1 Flashcards
What type of Reaction is Cellular Respiration?
Exothermic.
What is release from the Chemical process of Cellular Respiration?
Energy.
Organisms in general need Energy for: (3)
-Chemical Reactions, to build larger Molecules from smaller Molecules.
-Muscle Contractions, to allow for movement.
-Keeping warm, optimum Temp. for Enzyme activity.
Main uses of Energy in Human body: (6)
-Maintaining constant body Temperature (~37’).
-Cell Division + Growth.
-Active Transport.
-Protein Synthesis.
-Muscle Contractions.
-Passage of Nerve Impulses.
What type of Respiration is it when Glucose is reacted with Oxygen?
Aerobic Respiration.
Word Equation for Aerobic Respiration:
Glucose + Oxygen —–> Carbon Dioxide + Water (+Energy)
Symbol Equation for Aerobic Respiration:
C6H12O6 + 602 —–> 6CO2 + 6H2O (+Energy)
Where does Aerobic Respiration take place?
Mitochondria.
Respiration that occurs without Oxygen is called…
Anaerobic Respiration.
Glucose breakdown in Anaerobic Respiration is ___.
Incomplete.
Glucose breakdown in Aerobic Respiration is ___.
Complete.
When does Anaerobic Respiration occur?
When the body can’t supply enough Oxygen for Aerobic Respiration. Eg during exercise.
Word Equation for Anaerobic Respiration:
Glucose —–> Lactic Acid
Why is much less Energy Transferred from Anaerobic Respiration than in Aerobic Respiration?
Because the Oxidation of Glucose is incomplete in Anaerobic Respiration.
What is Produces from Anaerobic Respiration in Plants & Yeast? (2)
Ethanol, Carbon Dioxide.
