In this equation for photosynthesis, where does the first product come from? 6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆

• Carbon dioxide comes from the air.

• Oxygen is released as a gas after water is split

• Water is split to drive NADP to NADPH conversion.

• Glucose is formed right after the Calvin cycle.

What do osmosis and diffusion have in common?

• Both are the net movement of randomly moving molecules that makes concentration nearly equal on both sides of a bilayer membrane.

• Both processes occur through a semipermeable membrane called a concentration gradient.

• Both require the additional energy provided by an energy-carrying molecule, like ATP, to allow molecules to pass through the membrane.

• Both permit molecules of any kind, whether solute or solvent, to cross the bilayer membrane.

What is the correct description of the components of an ATP molecule?

• Nitrogen and carbon bond to an amino acid called adenine. The amino acid bonds to a double-ringed sugar molecule called ribose. Ribose bonds with three phosphate molecules.

• Adenine, an amino acid, bonds to a five-carbon sugar called ribose. The ribose molecule forms a bond with one phosphate. There are two other phosphate-phosphate bonds that complete the molecule.

• An amino acid called adenine bonds with a double-ringed sugar molecule called ribose. The ribose molecule forms a bond with one phosphate. There are an additional two phosphate-phosphate bonds to complete the molecule.

• Nitrogen in adenine, an amino acid, bonds with a series of three phosphate molecules. The phosphate molecules form the "tail of the molecule" and are also attached to ribose, a five-carbon sugar molecule.

What helps skin repair itself after it is cut?

• Interphase

• glycolysis

• mitosis

• meiosis

What is an important function of mitochondria?

• converting chemical energy from ATP into chemical energy in glucose products

• converting chemical energy from glucose into chemical energy in ATP

• converting energy from sunlight into chemical energy in glucose products

• converting energy from sunlight into chemical energy in ATP

Which picture illustrates the anaphase stage of mitosis?

• Picture A, where spindle fibers start to pull away from the center of the cell.

• Picture B, where nuclear membranes form around each set of chromosomes resulting in two nuclei.

• Picture C, where each pair of sister chromatids attaches to a spindle fiber by its centromere.

• Picture D, where chromosomes coil up, nuclear membrane breaks down, and spindle fiber system forms.
