10 Questions
Match the following terms with their description:
Active transport = Requires energy to move substances across a cell membrane Primary active transport = Directly uses energy, typically from ATP, to move molecules Symport system = Transports two different substances in the same direction Secondary active transport = Uses the energy stored in an electrochemical gradient to move substances Antiport system = Transports two different substances in opposite directions
Match the following systems with their characteristics:
Active transport = Moves substances against their concentration gradient Primary active transport = Involves the use of specific carrier proteins Symport system = Co-transports substances in the same direction Secondary active transport = Relies on the energy obtained from the movement of another molecule Antiport system = Exchanges one substance for another across a membrane
Match the following terms with their function:
Active transport = Maintains cell homeostasis by regulating internal concentrations of ions and molecules Primary active transport = Essential for processes like nerve impulse transmission and muscle contractions Symport system = Can lead to the accumulation of substances within a cell Secondary active transport = Can be coupled with primary active transport processes Antiport system = Involved in processes like nutrient absorption in the intestines
Match the following terms with their role in cellular function:
Active transport = Critical for nutrient uptake and waste removal in cells Primary active transport = Initiates the establishment of concentration gradients in cells Symport system = Important for signaling pathways and cell communication Secondary active transport = Works hand-in-hand with ion channels for cellular processes Antiport system = Contributes to maintaining proper pH levels within cells
Match the following terms with their impact on cellular energy usage:
Active transport = Consumes a significant portion of a cell's energy budget Primary active transport = Directly utilizes ATP molecules for its function Symport system = Requires energy input to transport substances together Secondary active transport = Indirectly relies on ATP production from mitochondria for energy needs Antiport system = Helps conserve some energy by exchanging substances

True
Simple cuboidal epithelium consists of flat, scale-like cells.
False
Simple squamous epithelium is a single layer of flattened cells.
True
Classification by shape of cells categorizes tissues based on the number of cell layers they have.
False
Classification by number of cell layers categorizes tissues based on whether they are composed of a single layer of cells or multiple layers.
True
