Which of the following statements is/are true regarding passive versus active transport? Click all that apply. Passive transport requires no energy input from the cell while active transport does. Active transport requires a transport protein while in passive transport, substances always move through the phospholipid bilayer. Active transport can move substances against their concentration gradient, but in passive transport, substances must move down their concentration gradient. Active transport is required for hydrophobic substances, while passive transport moves hydrophilic substances. Active transport allows cells to maintain internal concentrations of solutes that differ from concentrations in the environment, while passive transport does not. .

You are an astronaut that is going on a Space Exploration Mission to Mars. The mission is going well until you are hit by a fierce and completely unexpected dust storm. Your team needs to abort the mission and leave the planet immediately. As the crew members are trying to quickly board the ship, you get hit by an antenna and thrown off into the distance. Your team assumes that you are dead and leaves without youll The storm passes. You wake up and are thankful that you are alive but you quickly realize that you have been left alone on Mars!! You must now figure out how to survive until your crew returns to Mars on the next mission. You decide to grow potatoes as a food source. One day, as you are working on your farming project, you encounter a small creature. You realize that the creature has a ravenous appetite for potatoes!l You are immediately intrigued by this alien. You know it will be quite a while before a rescue mission arrives, so you decide to pass the time by trying to analyze the creature's bioenergetics pathway. During your research you realize that the alien has a similar cellular structure to organisms on Earth, having several of the same organelles. Surprisingly, the creature appears to be able to use the tiny amounts of Oxygen in the atmosphere for its metabolism. However, this creature is Silicon-based not Carbon-based. You also notice that this creature uses a triphosphate energy molecule which you name MTP because it is an unknown Martian triphosphatel You perform your biochemical analysis and come up with the following: Step \#1: A linear metabolic pathway begins using a molecule containing 270 Silicon atoms (Si i 270 ). This is the first molecule in the pathway. Twenty-seven MTP molecules are used up as Si 270 is broken down into three molecules of Si 90 - Nine molecules of a substance called ZADH are also formed during this step. Step \#2: Each Si 90 is further broken down. Six molecules of SiO 2 are released as the Si 90 breaks down into three molecules of Si 28 . Six MTP and seven ZADH molecules are also produced during this break down. Step \#3: Each Si 28 goes through a cyclic metabolic pathway. Each Si 28 is completely broken down to release 28 SiO 2 molecules. For each Si 28 that is broken down, 10 MTP , 5 ZADH , and 3 ZADH 2 are also produced. Step H4: The ZADH and ZADH 2 molecules are then further processed during a stage that appears to be similar to electron transport. During this stage, each molecule of ZADH will produce 8 MTP and each molecule of ZADH 2 will produce 6 MTP. NOTE: Each ZADH molecule produced during step \#1 will be converted into 2 molecule of ZADH 2 before it enters the electron transport stage (step \#4). Sketch the alien's metabolic pathway as it is described in steps 1,2, and 3 above (You do not need to draw step 4). (12 marks) Step 1: Sizx 3 sisa + 92ADH +27MTP Step 2: Sise 3 sia + 6 SiO 2 + 72 ADH + 6 M7P Step 3: Sia 28 1 O 2 + 10 M 7 P + 5 Z A DH + 32 A D H 2 During the complete metab.

Write the definition of the function insertBack() as a member function of the class AnyList as follows: - Parameter: An int storing a value. - The function creates a new node that stores the value passed by the parameter, and inserts the new node at the end of the list. Make sure you use the initializer list constructor. This way, you will be using only one function, which is more efficiend than using two (default constructor + setData).

Write the definition of a function printArray, which has two parameters. The first parameter is an array of integers and the second is an int, the number of elements in the array. The function does not return a value. Using a loop, the function prints out each element of the array, on a line by itself, in the order the elements appear in the array (first followed by second then third and so on) and adds the elements of the array. It also prints the total. .

With the worksheets still grouped, you want to insert a function to return the respective quarterly donation for a specific donor based on Donor ID. In cell L2, insert an INDEX function that uses the quarterly values array (range D2:G11). Nest an XMATCH function to look up the Donor ID in cell K 1 to find its position within the range A2:A11. Nest another XMATCH function to look up the quarter in cell K 2 to find its position within the range D1:G1. Keep the worksheets grouped. Now you want to display the cell address containing the quarterly donation displayed in cell L2. In cell L3, insert the ADDRESS function with nested XMATCH functions. The first nested function looks up the Donor ID in cell K 1 and compares it to the range A 1 : A 11 . The second nested function looks up the quarter entered in cell K2 and compares it to the range A1:G1. Display the resulting address as a relative reference. .

Why does ATP synthase need many different protein subunits? (a) Because it has multiple binding sites for allosteric modifiers. (b) Because it needs an intermembrane spanning domain, a rod, and subunits that can bind and squeeze ADP and Pi. (c) Because it binds protons, whereas simpler enzymes cannot bind protons. (d) Because it needs to bind ATP to drive a rotational movement. (e) Because it reaches from the intermembrane space into the cytosol, spanning a large distance. .
