Biology STAAR Review

Which of these statements best explains the process of energy conversion that takes place during cellular respiration in the mitochondria?

• Energy is required for carbon dioxide molecules to form six-carbon sugar molecules.

• Water molecules and radiant energy are necessary for anaerobic respiration to take place.

• Oxygen molecules release energy in the form of heat during combustion reactions.

• The energy in the bonds of glucose molecules is transferred to the phosphate bonds in ATP.

Which type of movement across a cell's plasma membrane requires energy supplied by ATP?

• Passive Transport

• Simple Diffusion

• Active Transport

• Osmosis

Which statement describes the process of osmosis in an animal cell?

• Sugar molecules move across the plasma membrane until the cell has enough energy to grow in size and divide.

• Water molecules move across the plasma membrane until solute concentrations are equal on both sides of the membrane.

• Ions move across the plasma membrane until the inside of the cell has a higher concentration of positive charges.

• Enzymes move across the plasma membrane until the cell has completed metabolism.

Which molecule synthesized by plants is a major source of energy for cellular processes in both plants and animals?

• Wax

• Nucleic Acid

• Glucose

• Chlorophyll

NGSS.HS-LS1-3

• Active transport, because energy is being used to move molecules against the concentration gradient

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis because energy is not being used to move molecules against the concentration gradient

• Energy conversions and synthesis of new molecules

• Synthesis of new molecules and homeostasis

• Transport of molecules and energy conversions

• Homeostasis and transport of molecules
