Nucleic Acids
Amino Acids
Fatty Acids
Simple Sugars
Which statement describes a property shared by lipids and carbohydrates?
Both dissolve in water
Both are sources of energy for a cell
Both have the same number of oxygen atoms
Both have the same number of carbon-hydrogen bonds
Scientist isolate an organic molecule that plays a role in digestion. When this polymer is not present, the rate of one of the chemical reactions required for digestion increases greatly. Which category of macromolecule are these scientists most likely studying?
carbohydrates
lipids
nucleic acids
proteins
What structural difference explains why lipids provide more energy to a cell than an equal mass of proteins or carbohydrates?
Lipids have more carbon-hydrogen bonds per gram than proteins or carbohydrates
Lipids have more nitrogenous bases per gram than proteins or carbohydrates
Lipids have more amino acids per gram than proteins or carbohydrates
Lipids have more simple sugars per gram than proteins or carbohydrates
Human heart cells require a constant release of energy to function continuously. Which structure would be numerous in such cells to meet this demand?
Golgi bodies
Nucleus
Mitochondria
Smooth Endoplasmic Reticulum
Which statement BEST compares the roles of organelles in making proteins?
Vesicles modify proteins, while the Golgi bodies manufactures proteins
Rough ER transports proteins, while the cell membrane modifies proteins
Chromosomes modify proteins, while the nuclear membrane produces proteins
Ribosomes produce proteins, while the nucleus contain protein blueprints
Which statement BEST justifies the comparison of a cell's nucleus to a person's brain?
Both store information and control activities
Both are encased in a hard, protective coating
Both are involved in producing energy-containing molecules
Both are directly involved in transporting wastes so they do not build up
Which statement BEST distinguishes the roles of chloroplasts and mitochondria in maintaining homeostasis in a cell?
Chloroplasts regulate movement of materials in plants cells; mitochondria regulate movement of materials in animal cells
Chloroplasts produce glucose molecules; mitochondria break down glucose molecules
Chloroplasts break down proteins; mitochondria generate new proteins
Chloroplasts store water and wastes; mitochondria provide support for the cell
