Question
1. There are 6 different cards. Sort the cards into two groups. Each card should be sorted into one and only one group. Explain how you sorted your cards into the two groups.
CARD 1 CARD 2 Rhodopsin is a light-sensing protein. It has multiple hydrophobic regions in its structure that allow it to interact with the hydrophobic components of membranes. After processing in the Golgi, rhodopsin is embedded in vesicle membranes and relocated to the cellular membrane. The protein Estrogen Receptor 3 is a receptor for signals from outside the cell. Its slightly positive alpha helices allow it to bind to DNA, which is negatively charged. After leaving the Golgi, Estrogen Receptor B responds to signals by moving to the nucleus and interacting with DNA. CARD 3 Histones are proteins that bind to and organize DNA. Some positively charged alpha helices in the histone interact with the negatively charged phosphate groups of DNA. After histones are processed, they are localized to the nucleus where they organize DNA. Oxytocin receptor is a protein that receives extracellular oxytocin signals. It has hydrophobic regions in its protein structure that tend to associate with other hydrophobic molecules. When leaving the Golgi, oxytocin receptors are transported in the membranes of vesicles to the cellular membrane The protein Thyroid Receptor ß 1 is a receptor for extracellular signals. It has a few positively charged regions, and these charged regions are attracted to the negative charge on DNA. After processing in the Golgi, Thyroid Receptor 3 1 is able to promote gene expression in the nucleus Glucose transport proteins move sugar from one side of a membrane to another. Their structures contain alpha helices with several hydrophobic amino acids, which allow for glucose transport proteins are incorporated in the membranes of many cell types.Explanation / Answer
Group 1- Card 1, Card 3, Card 6
Group 2- Card 2, Card 4, Card 5
Here, group 1 is the group of proteins. Card 1 describes about the rhodopsin which is a protein. Card 3 describes abiut histones which are also proteins. Card 6 describes about the protein involved in glucise teansport.
Group 2 consists of receptors. Card 2 is referring about the estrogen receptor, Card 4 is about ocytocin receptor and Card 5 is about the thyroid receptor.
