4.1 Quiz photosynthesis

Select the option that best answers the questions or completes the statement. Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery.

• DNA
• RNA
• ATP
• CMP

Select the option that best answers the questions or completes the statement. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.

• nucleotide
• oxygen
• phosphate
• ribose

Select the option that best answers the questions or completes the statement. Plants, algae, and some bacteria use the energy of sunlight in the process of (herbivory / respiration / photoperiodism / photosynthesis).

• herbivory
• respiration
• photoperiodism
• photosynthesis

Select the option that best answers the questions or completes the statement. The process converts the energy from sunlight into chemical energy stored in the bonds of (carbon dioxide / carbohydrates / proteins / water molecules).

• carbon dioxide
• carbohydrates
• proteins
• water molecules

Which statement best describes the relationship between adenosine diphosphate (ADP) and adenosine triphosphate (ATP)?

• With an input of energy, ADP rearranges to become ATP.
• Without any energy change, ADP rearranges to become ATP.
• With an input of energy, ADP combines with a phosphate group to become ATP.
• With a release of energy, ADP combines with a phosphate group to become ATP.

Which of the following organisms can perform photosynthesis?

• Animals only
• Plants only
• Plants, algae, some bacteria, some protists
• Only plants and animals

Where in plants do carbon dioxide and oxygen enter/exit?

• Root tips
• Stem
• Flowers
• Stomata of leaves

Light supplies the energy for photosynthesis. What is the overall chemical reaction?

• Oxygen and water are converted into glucose sugar and carbon dioxide.
• Carbon dioxide and water are converted into glucose sugar and oxygen.
• Sugar is broken into water and oxygen.
• Carbon dioxide and oxygen are converted into glucose sugar and water

The diagram shows the molecular structure of adenosine triphosphate (ATP) Which of these events occurs during the normal function of ATP in the cell?

• A chemical bond forms between the adenine unit and the third phosphate group.
• The chemical bond breaks between the adenine and ribose units.
• The chemical bond breaks between the ribose unit and the first phosphate group.
• The chemical bond breaks between the second and third phosphate groups.

Chloe is developing a model of photosynthesis. The first part of the model is shown below. Which would be the MOST useful next step for Chloe to develop the photosynthesis model further?

• Extend the lines for sunlight so that they pass through the autotroph.
• Represent a chemical reaction in the autotroph that produces high-energy carbohydrates.
• Represent a chemical reaction in the autotroph that produces high-energy proteins.
• Draw a circle to represent a heterotroph, and draw a line to connect it to the autotroph.
