Fatty Acids
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.
Scientists isolate an organic macromolecule 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 macromolecules are these scientists most likely studying?
Carbohydrates
Lipids
Nucleic Acids
Proteins
Which statement best distinguishes the roles of chloroplasts and mitochondria in maintaining homeostasis in a cell?
Chloroplasts regulate movement of materials in plant 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.
Chloroplast stores water and wastes; mitochondria provide support for the cell.
How do the chloroplasts and mitochondria interact to maintain homeostasis in a plant cell?
These organelles are both important for the uptake of nutrients from the cell's exterior.
These organelles are both important in the regulated transport of molecules within cells.
These organelles are both important because glucose produced by the chloroplast enters the mitochondria to be converted into energy.
These organelles are both important for the use of cellular genetic information to make proteins.
Which of the following accurately relates the structure of a macromolecule to its function?
Lipids are composed of sugars that act as energy storage.
Proteins are composed of glycerol and fatty acids that act as insulation.
DNA is composed of nucleotides that store an essential genetic blueprint for organisms.
Carbohydrates are composed of amino acids that fold into protein/enzymes that speed up chemical reactions in cells.
Carbohydrates are composed of amino acids that fold into protein/enzymes that speed up chemical reactions in cells.
