Unit 2-Cellular Energy Review Flashcards
What are the reactants of photosynthesis?
Carbon Dioxide, Water, Sunlight
What are the products of photosynthesis?
Glucose, Oxygen
2 stages of photosynthesis
-Light dependent
-Light Independent
Light Dependent Stage
Takes place in thylakoid membrane and grana
Light absorbed by chlorophyll
ATP is synthesized in thylakoid
Light Independent Stage
happens in stroma
glucose is produced
The rate of photosynthesis depends on…
temperature, Amount of light
photosynthesis formula
CO2+H2O+light → C6H12O6 + O2
What cell structure is involved in photosynthsis?
Chloroplast
2 types of cellular respiration
Aerobic Respiration, Anaerobic Respiration
Aerobic Respiration Formula
C6H12O6 + O2 → CO2 + H2O + 36 ATP
Aerobic Respiration
Cells break apart glucose to release energy, involves oxygen
Glycolysis
-Splitting glucose molecules,
-4 ATP produced,
-does not include oxygen
-Happens in cytoplasm
Citric Acid Cycle (Kreb Cycle)
-Gain of 36 ATP
-Happens in mitochondria
-Produces CO2 as waste product
Reactants involved in Aerobic Respiration
Glucose, oxygen
Products of Cellular respiration
36 ATP, Carbon Dioxide, Water
What cellular structure is involved in Aerobic Respiration?
Mitochondria
Anaerobic Respiration (Fermentation)
Glucose is broken down in a process not involving oxygen
2 Types of Anaerobic Respiration
Lactic Acid Fermentation, Alcoholic Fermentation
Lactic Acid Fermentation Formula
C6H12O6→ Lactic acid + CO2 + 2 ATP
Alcoholic Fermentation Formula
C6H12O6→ Alcohol (ethanol) + CO2 + 2 ATP
Lactic Acid Fermentation
A type of Anaerobic respiration that takes place in animals when there is not enough oxygen present, why our muscles get sore
Alcoholic Fermentation
Anaerobic Respiration that takes place in yeast and bacteria, gives off CO2
Where dose Anaerobic Respiration Occur?
Cytoplasm
Reactants involved in Alcoholic Fermentation
Glucose
Products involved in Alcoholic Fermentation
Alcohol, CO2, 2 ATP
Reactants Involved in Lactic Acid Fermentation
Glucose
Products involved in Lactic Acid fermentation
Lactic Acid, CO2, ATP
What is more efficient Aerobic or Anaerobic respiration?
Aerobic, it produces 36 ATP as appose to 2
What levels of cellular organization are found in living things.
Organism, organ system, organ, tissue, cell
What type of cells are stem cell?
Undifferentiated cells
What is cell specialization?
Cells that express different genes in order to perform different functions
