Cells and their Processes

Which structure is correctly paired with its function?

• Mitochondria-movement

• vacuole-cell division

• nucleus-ships proteins

• Ribosomes-protein synthesis

Why do you believe chloroplasts are mostly found in the leaves of plants?

• To prevent evaporation

• To interfere with the xylem and phloem

• To absorb more oxygen

• To absorb more light

How do molecules enter the cell when they have to move against the concentration gradient?

• passive transport through osmosis

• passive transport through diffusion

• phagocytosis

• active transport using ATP

What is the function of ATP?

• Aids in protein folding and coiling

• lowers the activation energy of reactants

• used to store and transfer energy

• helps maintain fluidity of cell membrane

What process occurs in muscles when oxygen levels are low?

• As cells run out of oxygen, they will make the same amount of ATP.

• The flow of oxygen will remain the same as long as you keep breathing.

• Cells will use anaerobic respiration and make small amounts of ATP in the absence of oxygen.

• The cells will run out of oxygen and die.

How do bacteria transfer energy for movement?

• They use the mitochondria to generate energy for movement

• They use cellular respiration to produce ATP, whose energy moves to the flagella.

• Enzymes lower activation, which moves the flagella.

• The bacteria cell's mitochondria makes proteins to move the flagella.

How are photosynthesis and cellular respiration related?

• The products of photosynthesis are the reactants of respiration

• The products of photosynthesis inhibit respiration.

• The reactants of photosynthesis are the reactants of respiration.

• The products of photosynthesis are the products of respiration.

How are photosynthesis and cellular respiration different?

• Respiration stores ATP, photosynthesis releases ATP.

• Respiration produces oxygen, photosynthesis used oxygen.

• Photosynthesis releases energy, respiration stores energy

• Photosynthesis uses carbon dioxide, cellular respiration produces carbon dioxide.

Which statement is true about cellular respiration

• Plant and animal cells perform cellular respiration

• Only plant cells perform cellular respiration

• Only animal cells perform cellular respiration

• Neither plant or animal cells perform cellular respiration.

The picture is an example of...

• active tranport
• passive transport
• diffusion
• osmosis
