Which statement is true?
A. Carbohydrates are made of amino acids.Incorrect. The monomer the carbohydrates are monosaccharides.
B. Lipids space made the monosaccharides.Incorrect. Lipids room made that glycerol and also fatty acids.
C. Nucleic Acids room made of nucleotides. Correctly! The structure blocks of nucleic acids space nucleotides.
D. Proteins space made of nucleic acids. Incorrect. Proteins room made of amino acids.
Which the the adhering to combinations of organic link is mistakenly matched with its function?
A. Carbohydrate – main source of power for living things Incorrect. Carbohydrates are the main resource of energy for living things. The inquiry stem asks girlfriend to discover the combination that is incorrectly matched.
B. Lipid - warehouse of energy and transport of materials in and also out the a cell Incorrect. Lipids primary role is the warehouse of energy and the move of materials right into out that a cell. The concern stem asks friend to find the combination that is wrongly matched.
C. Protein – provides power for the cabinet Correct! The concern stem asked for the untrue match. Protein main duty is structure and also support.
D. Nucleic mountain – stores and transmits genetic information Incorrect. Main point acids to store and transmit genetic information. The question stem asks friend to uncover the mix that is incorrectly matched.
The diagram is an instance of a molecule the is insoluble in water and is a significant component of cell membranes. This diagram illustrates a(n) _____
A. Nucleic mountain Incorrect. This is not a nucleic acid. Look at again closely at the structure; notice the lengthy chains of carbon and also hydrogen atoms. Also, the stem says that this biomolecule is a major component of cell membranes; main point acids space not a major component of cell membranes.
B. Lipid correct! This chart does highlight a lipid. Lipids space insoluble in water and also a major component of cell membranes. Lipids can be easily established by the long chains the carbon and also hydrogen.
C. Protein Incorrect. This diagram walk not show a protein. This one is tricky due to the fact that proteins space a ingredient of cell membranes. But, look again carefully at the diagram; an alert the long chains the carbon and hydrogen atoms.
D. Carbohydrate Incorrect. This diagram does not illustrate a carbohydrate. Carbohydrates room composed the carbon, hydrogen and also oxygen prefer the biomolecule illustrated here. Notification the long chains of carbon and hydrogen this is a properties of another biomolecule. Also, the stem states this biomolecule is a significant component of cabinet membranes. Carbohydrates room not a significant component of cell membranes.
Use the diagram and the information listed below to answer inquiry 4.
Which that the following are exactly descriptions of the macromolecule pictured?
A. I and III onlyIncorrect. I is no correct together this is no a lipid. III is correct. This macromolecule is written of carbon, hydrogen, and oxygen.
B. III and also IV only Correct! This macromolecule is written of carbon, hydrogen and also oxygen. IV is also correct. The macromolecule have the right to be damaged down right into 5 glucose molecules.
C. III only Incorrect. III is correct. This macromolecule is written of carbon, hydrogen and also oxygen. But is this the only statement that is correct?
D. II and IV only Incorrect. II is no correct. This molecule is no the key component of enzymes and also hormones. IV is correct. The macromolecule can be damaged down into five glucose molecules.
A college student was request to identify three unknown substances and determine which problem a person would desire to consume the night before running a marathon so that they had a big energy supply accessible for the run. His data is displayed below.
After examining the data, the student concluded the the person would desire to eat substance A the night before a race.
Was the college student correct in his conclusion and why?
A. Yes, the college student was correct due to the fact that the main duty of lipids is power supply. Incorrect. Lipids main duty is not power supply.
B. No, the student was no correct. That should have actually chosen B due to the fact that proteins room the main resource of power for living organisms. Incorrect. Proteins are not the main resource of energy for life organisms.
C. No, the student was no correct. The should have actually chosen problem C due to the fact that the main function of carbohydrates is power supply because that living organisms. Correctly! Carbohydrates room the main resource of power for living organisms
D. No, the student was no correct. He should have chosen problem D because it consists of both lipids and proteins. Incorrect.
