5.2 Respiration

• Respiration can be classified into two types: aerobic and anaerobic
• What role does ATP play in respiration?

  Energy currency
• Aerobic respiration produces more ATP than anaerobic respiration.


  True
• Steps of respiration in the correct order

  1️⃣ Oxidation of glucose

  2️⃣ Reduction of electron carriers

  3️⃣ ATP production through electron transport chain

  4️⃣ Two types: aerobic and anaerobic
• Anaerobic respiration produces 38 ATP per glucose molecule.

  False
• What are the products of aerobic respiration?

  Carbon dioxide and water
• Anaerobic respiration produces the same amount of ATP as aerobic respiration.

  False
• Stages of aerobic respiration in the correct order

  1️⃣ Glycolysis

  2️⃣ Link Reaction

  3️⃣ Krebs Cycle

  4️⃣ Oxidative Phosphorylation
• The Krebs Cycle produces ATP, CO2, NADH, and FADH2
• What is the energy currency of cells?

  ATP
• Aerobic respiration requires oxygen.


  True
• Aerobic respiration produces approximately 38 ATP per glucose molecule.
• What are the inputs of glycolysis?

  Glucose, ATP, NAD+
• Stages of aerobic respiration in the correct sequence.

  1️⃣ Glycolysis

  2️⃣ Link Reaction

  3️⃣ Krebs Cycle

  4️⃣ Oxidative Phosphorylation
• Match the type of fermentation with its product in anaerobic respiration.

  Lactic acid fermentation ↔️ Lactic acid

  Alcoholic fermentation ↔️ Ethanol and CO2
• Aerobic respiration occurs in the mitochondria, while anaerobic respiration occurs in the cytoplasm.


  True
• What is respiration defined as in biology?

  Metabolic process to release ATP
• Aerobic respiration requires oxygen to function.

  True
• Anaerobic respiration occurs in the cytoplasm
• Where does respiration occur in cells?

  Mitochondria
• Aerobic respiration requires oxygen
• Match the type of respiration with its location:

  Aerobic Respiration ↔️ Mitochondria

  Anaerobic Respiration ↔️ Cytoplasm
• In anaerobic respiration, glucose is broken down incompletely
• Where does glycolysis occur in aerobic respiration?

  Cytoplasm
• What is the role of NADH in aerobic respiration?

  Electron carrier
• ATP is the energy currency of cells.

  True
• Respiration is a metabolic process that breaks down glucose to release energy in the form of ATP
• What are the products of aerobic respiration?

  Carbon dioxide, water, ATP
• Anaerobic respiration occurs in the cytoplasm.


  True
• The Krebs cycle occurs in the mitochondrial matrix.
• Glycolysis is a stage in both aerobic and anaerobic respiration.


  True
• In animals, lactic acid fermentation occurs when muscles lack oxygen.
• How many ATP molecules are produced in anaerobic respiration per glucose molecule?
