Question

Responses

DNA codes for proteins that determine which processes and functions a cell carries out.
DNA codes for proteins that determine which processes and functions a cell carries out.

DNA is used to produce ATP during cellular respiration, creating energy that the cell needs.
DNA is used to produce ATP during cellular respiration, creating energy that the cell needs.

DNA performs several functions in the cell such as transporting molecules and protecting the body.
DNA performs several functions in the cell such as transporting molecules and protecting the body.

DNA binds itself to proteins in the cell membrane to act as an identifier for the cell.

Answer 1

The correct response is:

DNA codes for proteins that determine which processes and functions a cell carries out.

This statement accurately describes the relationship between nucleic acids, specifically DNA, and the function of cells. DNA contains the genetic instructions for the synthesis of proteins, which play critical roles in various cellular processes and functions.

Answer 2

Which compound is a reactant of both cellular respiration and dehydration synthesis?(1 point)
Responses

glucose
glucose

water
water

ATP
ATP

oxygen

Answer 3

The correct response is:

water

Water is a reactant in dehydration synthesis (where it is removed to form bonds between molecules) and is also produced in cellular respiration, particularly during the electron transport chain stage. It is not a direct reactant in the overall equation for cellular respiration, but it plays a crucial role in the process.

Answer 4

Which step in cellular respiration produces the most ATP?(1 point)
Responses

electron transport chain
electron transport chain

Krebs cycle
Krebs cycle

glycolysis
glycolysis

lactic acid fermentation

Answer 5

The correct response is:

electron transport chain

The electron transport chain produces the most ATP during cellular respiration, generating approximately 26 to 28 ATP molecules per glucose molecule, while the Krebs cycle and glycolysis produce significantly fewer ATP. Lactic acid fermentation does not produce ATP in the same quantity as the other processes.

Answer 6

By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not?(1 point)
Responses

This is not true because plants need to sequester nitrogen from the soil to build amino acids.
This is not true because plants need to sequester nitrogen from the soil to build amino acids.

This is not true because plants need to perform cellular respiration to break down the glucose into carbon, hydrogen, and oxygen.
This is not true because plants need to perform cellular respiration to break down the glucose into carbon, hydrogen, and oxygen.

This is true because photosynthesis produces glucose, which has carbon, hydrogen and oxygen—the building blocks for all biomolecules.
This is true because photosynthesis produces glucose, which has carbon, hydrogen and oxygen—the building blocks for all biomolecules.

This is true because photosynthesis produces glucose, and plants only need sugars, not amino acids or fatty acids.

Answer 7

The correct response is:

This is not true because plants need to sequester nitrogen from the soil to build amino acids.

While photosynthesis produces glucose, which is a source of carbon, hydrogen, and oxygen, plants also need nitrogen to synthesize amino acids, which are essential for proteins. Therefore, they cannot rely solely on photosynthesis to build all biomolecules.

Answer 9

The correct response is:

nucleic acids.

The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.

Answer 10

What process must occur for carbon, hydrogen, and oxygen atoms from sugar molecules to combine with other elements to form amino acids?(1 point)
Responses

Sugar molecules must be rearranged through metabolic pathways to form amino acids.
Sugar molecules must be rearranged through metabolic pathways to form amino acids. - no response given

Sugar molecules must undergo photosynthesis to produce energy, which can drive amino acid synthesis.
Sugar molecules must undergo photosynthesis to produce energy, which can drive amino acid synthesis. - no response given

Sugar molecules must be stored as fat to be later converted into amino acids.
Sugar molecules must be stored as fat to be later converted into amino acids. - no response given

Sugar molecules must undergo hydrolysis so they can react with nitrogen to form amino acids.

Answer 11

The correct response is:

Sugar molecules must be rearranged through metabolic pathways to form amino acids.

This statement accurately reflects that sugar molecules can serve as intermediates in metabolic pathways, which can undergo various transformations to ultimately contribute to the synthesis of amino acids.
