In biological systems, there are several membrane transport systems responsible for the passage of ions like Na and K, or small molecules like glucose and amino acids, through biological membranes. Classify each membrane transport system as either a primary active transporter, a secondary active transporter, or a passive transporter. a. primary active transporterb. secondary active transporter. c. a passive transporter1. the Ca^2+ ATPase of the sarcoplasmic reticulum. 2. the Na^+/K^+ ATPase of plasma membranes.
3. the amino acid- Na^+ transporter of kidney cells.
4. the glucose- Na^+ transporter of intestinal epithelial cells.
5. the glucose transporter of erythrocytes. Which transport systems utilize a chemical reaction for the energy source? a. the Ca^2+ ATPase of the sarcoplasmic reticulum. b. the Na^+/K^+ ATPase of plasma membranes. c. the amino acid- Na^+ transporter of kidney cells. d. the glucose- Na^+ transporter of intestinal epithelial cells. e. the glucose transporter of erythrocytes.
