Which organelle will give off oxygen and use up carbon dioxide in plants?

• Mitochondria
• Chloroplasts
• Endoplasmic reticulum
• Golgi apparatus

Which of the following would be a function of the peroxisomes?

• Regulating blood sugar levels
• Breaking down fatty acids, detoxifying harmful substances, and participating in the synthesis of bile acids and plasmalogens
• help germinating seeds convert fatty acids into molecules that can be converted to sugars

  
  

• Storing excess water

If the mitochondrion is the result of endosymbiosis, which membrane of the mitochondrion represents the engulfing vesicles

• inner membrane
• the outer mitochondrial membrane

  
  

• nuclear membrane
• outer membrane

Proteins are processed and modified in the interior of the

• nucleus
• rough endoplasmic reticulum.

  
  

• mitochondria
• cytoplasm

A compound would make a good antibiotic if it affects a structure or process only found in bacterial cells and not in our eukaryotic cells.

Which of the following actions would theoretically make a good antibiotic?

• Targeting a structure or process only found in eukaryotic cells
• Targeting a structure or process only found in bacterial cells
• prevents repair of the peptidoglycan cell wall.

• Targeting a structure or process found in both bacterial and eukaryotic cells

Both plant and animal cells have mitochondria because they both

• require energy to carry out their functions
• need ATP for energy.

• lack a nucleus
• use photosynthesis

Which of the following is the largest eukaryotic organelle?

• endoplasmic reticulum
• mitochondria
• nucleus
• lysosome

Which of the following is a function of the cytoskeleton?-

• Structural support, cell movement, intracellular transport
• Energy production
• anchors organelles in place within a cell

• Cell communication

Which of the following would be considered evidence that chloroplasts are involved in photosynthesis?

• Presence of hemoglobin within chloroplasts
• Absence of chlorophyll within chloroplasts
• Isolated chloroplasts give off oxygen when exposed to sunlight.

• Presence of chlorophyll within chloroplasts

If an active cell produces an important protein for secretion, what is the correct sequence of organelles that are involved in the production of the protein?

• Ribosomes -> Lysosomes -> Golgi Apparatus -> Vesicles
• Mitochondria -> Endoplasmic Reticulum -> Golgi Apparatus -> Vesicles
• -ribosomes -+ endoplasmic reticulum - Golgi apparatus.

• Ribosomes -> Golgi Apparatus -> Endoplasmic Reticulum -> Vesicles
