Respiration & Glycolysis

Type of metabolism that breaks down large molecules into smaller molecules.

• Anabolism
• Metabolism
• Synthesis
• Catabolism

Energy from sunlight is then converted into chemical energy in the form of organic molecules.

• Photosynthesis
• Mitosis
• Respiration
• Chlorophyll

Inside the cell, the energy from organic molecules (food) is unlocked and transferred to ATP.

• Photosynthesis
• Mitosis
• Cellular respiration
• Glycolysis

ATP is a nucleic acid that consists of:

• thymine, deoxyribose sugar, and three phosphate groups
• guanine, ribose sugar, and two phosphate groups
• cytosine, deoxyribose sugar, and two phosphate groups
• adenine, ribose sugar, and three phosphate groups

Correct statements about mitochondria.

• Has single membrane, circular DNA, and 80S ribosomes

• Has single membrane, linear DNA, and 70S ribosomes

• Has double membrane, circular DNA, and 70S ribosomes

• Has double membrane, linear DNA, and 80S ribosomes

The difference between the aerobic and anaerobic respiration, EXCEPT.

• Aerobic respiration requires oxygen, anaerobic respiration does not
• Aerobic respiration produces more ATP than anaerobic respiration
• Anaerobic respiration is faster than aerobic respiration
• Aerobic respiration occurs in plants only

Correct sequence of aerobic respiration.

• Glycolysis -> Link Reaction -> Electron Transport Chain (ETC) -> Krebs cycle

• Electron Transport Chain (ETC) -> Link Reaction -> Glycolysis -> Krebs cycle

• Glycolysis -> Link Reaction -> Krebs cycle -> Electron Transport Chain (ETC)

• Krebs cycle -> Glycolysis -> Electron Transport Chain (ETC) -> Link Reaction

Correct location of steps in aerobic respiration.

• Glycolysis in the nucleus, Krebs cycle in the cytoplasm, Electron transport chain in the cell membrane
• Glycolysis in the mitochondria, Krebs cycle in the cytoplasm, Electron transport chain in the nucleus
• Glycolysis in the cytoplasm, Krebs cycle in the mitochondria, Electron transport chain in the inner mitochondrial membrane
• Glycolysis in the cytoplasm, Krebs cycle in the cell membrane, Electron transport chain in the nucleus

Materials needed in glycolysis:

• Fructose, ADP, NADH

• Fructose, ATP, FADH2

• Glucose, ATP, NAD

• Glucose, ADP, NADH

Net products of glycolysis

• 3 ATP, 1 NADH, 3 pyruvate
• 1 ATP, 3 NADH, 1 pyruvate
• 4 ATP, 2 NADH, 1 pyruvate
• 2 ATP, 2 NADH, 2 pyruvate
