Carrier - Welcome Quiz

Welcome, Carlos! One late summer day, Carlos sat at the kitchen table. He wanted to begin his poster. He had found paper, glue, and colored markers. He had a box of family photoS. But what should I put on it? he thought. Soon, Carlos would start school in a new town, in a new country. He had just met his new school principal. "You can bring this poster on the first day of school, Carlos," his principal had said. "This will help the kids get to know you." Carlos picked photos of his family. He added one of their old home in Monterrey, Mexico. He wrote about the books, sports, and foods he liked. He carried his poster across the hall of his apartment building. He knocked on the door, and a smiling girl opened it. "Hola, Carlos!" said Maria. "Hola, Maria," said Carlos. "Do you want to see my poster? It's for the first day of school." "Oh, yes!" said Maria. Carlos spread out the poster. "This is a photo of my parents," Carlos explained. "This is our house. These are the mountains in Monterrey." "My padre works for a big solar energy company from Monterrey. They moved us to the United States to open a new factory here." "Monterrey looks beautiful, Carlos," said Maria. "It was sunny and a great place to do things outdoors," Carlos said. "Was it hard to leave your relatives?" Maria asked. "Yes, but we'll go back during the holidays to visit them," said Carlos. Maria looked at another photo. "That's my older brother, Mateo. This is my little sister, Selena," Carlos said. "My abuela will come to live with us soon, too." Maria read that Carlos liked to play baseball. "You could join our baseball team!" said Maria. "That would be fun," said Carlos. He showed Maria his best batting swing. "That's a good hit, for sure!" laughed Maria. Then Maria brought out crayons and markers. Together they colored the rest of the poster. "There's something I want to add," said Carlos. Carlos drew a picture of a smiling girl. She had long, soft hair. "Is that your friend in Monterrey?" asked Maria. "No, it's my first friend in America!" said Carlos.

Carrier mediated transport

Genetic Testing: Types of carrier screening, Reasons for screening

Wave as energy carrier

In many cases, cells must move materials from an area of lower concentration to an area of higher concentration, or “up” their concentration gradient. Such movement of materials is known as active transport. Unlike passive transport, active transport requires a cell to expend energy. CELL MEMBRANE PUMPS Ion channels and carrier proteins not only assist in passive trans- port but also help with some types of active transport. The car- rier proteins that serve in active transport are often called cell membrane “pumps” because they move substances from lower to higher concentrations. Carrier proteins involved in facilitated diffusion and those involved in active transport are very similar. In both, the molecule first binds to a specific kind of carrier protein on one side of the cell membrane. Once it is bound to the molecule, the protein changes shape, shielding the molecule from the hydrophobic interior of the phospholipid bilayer. The protein then transports the molecule through the membrane and releases it on the other side. However, cell membrane pumps require energy. Most often the energy needed for active transport is supplied directly or indirectly by ATP. Sodium-Potassium Pump One example of active transport in animal cells involves a carrier protein known as the sodium-potassium pump. As its name sug- gests, this protein transports Na ions and K ions up their con- centration gradients. To function normally, some animal cells must have a higher concentration of Na ions outside the cell and a higher concentration of K ions inside the cell. The sodium- potassium pump maintains these concentration differences. Follow the steps in Figure 5-6 on the next page to see how the sodium-potassium pump operates. First, three Na ions bind to the carrier protein on the cytosol side of the membrane, as shown in step . At the same time, the carrier protein removes a phosphate group from a molecule of ATP. As you can see in step , the phos- phate group from the ATP molecule binds to the carrier protein. Step shows how the removal of the phosphate group from ATP supplies the energy needed to change the shape of the carrier pro- tein. With its new shape, the protein carries the three Na ions through the membrane and then forces the Na ions outside the cell where the Na concentration must remain high. 3 2 1 SECTION 2 OBJECTIVES ● Distinguish between passive transport and active transport. ● Explain how the sodium-potassium pump operates. ● Compare endocytosis and exocytosis.

When the K ions bind, the phosphate group is released, as indicated in step , and the carrier protein restores its original shape. As shown in step this time, the change in shape causes the carrier protein to release the two K ions inside the cell. At this point the carrier protein is ready to begin the process again. Thus, a complete cycle of the sodium-potassium pump transports three Na ions out of the cell and two K ions into the cell. At top speed, the sodium-potassium pump can transport about 450 Na ions and 300 K ions per second. The exchange of three Na ions for two K ions creates an electrical gradient across the cell membrane. That is, the outside of the membrane becomes positively charged relative to the inside of the membrane, which becomes relatively negative. In this way, the two sides of the cell membrane are like the positive and nega- tive terminals of a battery. This difference in charge is important for the conduction of electrical impulses along nerve cells. The sodium-potassium pump is only one example of a cell membrane pump. Other pumps work in similar ways to transport important metabolic materials across cell membranes.

Communication is the process of passing information, news, ideas or feelings from one person to another. For communication to take place, there must be a sender and a receiver of the message. System of communication is the different ways in which messages are sent and received. THE FOLLOWING ARE THE MAIN MEANS OF COMMUNICATION: 1.Traditional means: These are the means used to pass ideas or information in the past. The following are the various means used: Drumming, Message Carrier, Town Criers, Smoke Signal, Gun Shots, sending of symbolic items (such as a gun or bullets to announce war, Sponge and Soap to announce the safe delivery of a pregnant woman). 2. Modern means: These are the means used to pass ideas or information in the present day. The following are the various means used: Radio, Television, Telephone, Newspapers and Magazines, The Internet, Fax machine, Handsets, Telegram, Satellite, Road signs, Posters and billboards. DIFFERENCES BETWEEN TRADITIONAL AND MODERN MEANS OF COMMUNICATION. Traditional means Modern means 1.It makes use of local items such as drum, gong etc. It makes use of modern technology 2.Messages cannot travel very long distances. Messages can travel far and wide. 3. Delivery of message is slow. It may take days or weeks or months. Delivery of message is faster. Can reach the recipient within seconds. 4. It is cheaper It is very expensive. 5.It does not use electricity. It uses electricity. A recipient is the person or people receiving a message. While the sender is the person or people who sends the message.

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet. A modem is a network device that both modulates and demodulates analog carrier signals (called sine waves) for encoding and decoding digital information for processing. A hub is a physical layer networking device which is used to connect multiple devices in a network.
