Front

What event occurs during the normal function of adenosine triphosphate (ATP) in the cell? Options: 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.

Back

The chemical bond breaks between the second and third phosphate groups.

Front

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

Back

With an input of energy, ADP combines with a phosphate group to become ATP.

Front

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?

Back

Represent a chemical reaction in the autotroph that produces high-energy carbohydrates.

Front

A mushroom gains its energy by decomposing the tissues of dead organisms. Should mushrooms be classified as autotrophs, heterotrophs, in both groups, or in neither group, and for what reason?

Back

They are heterotrophs because their food is made by other organisms.

Front

What describes the role of energy in the process where neurons pump sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell?

Back

The process requires energy that is provided by ATP.

Front

During photosynthesis, cells capture the energy of sunlight using chlorophyll, which is a type of pigment. Photosynthesis also relies on a compound called _________________ , which is an electron __________ that accepts and transfers high-energy electrons.

Back

NADP +, source

Front

During photosynthesis, cells capture the energy of sunlight using ( thylakoid / stroma / NADPH / chlorophyll ) , which is a type of ( nucleotide / carbohydrate / hormone / pigment ) . Photosynthesis also relies on a compound called ( ATP synthase / NADP + / glucose / DNA ) , which is an electron _____________________ that accepts and transfers high-energy electrons.
