Sperm need significant amounts of ATP to fuel their travel through the reproductive tract. This ATP is generated via oxidative metabolism of the glucose and fructose contained in the seminal fluid. These sugars are large polar molecules that enter sperm cells via glucose transporters or GLUTS. One such GLUT protein is depicted in the image below. When GLUTS recognize and bind glucose, they undergo a conformational change releasing glucose on the other side of the membrane. Due to the persistent high energy demands of the sperm cell, these sugars are continually being catabolized (broken down). GLUTs mediate what type of transport of glucose and fructose across the membrane? ________________ Is this an active or passive process? _________________ What type of transport protein are the GLUTs described in this question? ___________________ How many transmembrane domains does this GLUT have? _______________
