Active Transport Vs Sodium Potassium Pump
Energy was used to set up the ion gradient and that is why there are more sodium ions outside the membrane than the inside. The sodium ions are transported forcefully outside the cell membrane and the potassium ions are transported forcefully inside the cell membrane. The energy that is used for this is in the form of ATP which is broken down into ADP + P2. This is known as a sodium potassium pump. This process is called an active transport which means that it uses energy by breaking down a molecule of ATP. This is a primary active transport as ATP was directly used. The food that we eat goes into the gut, and if the food is sweet that it contains glucose but if it is salty then it would contain sodium. The intestines are guts that are lined

The following experiment was designed to utilize this principle in order to determine the tonicity of a set group of solutions, as they related to eggs. In this experiment, decalcified eggs were placed into four different solutions, with mass measurements of the egg taken at fifteen minute intervals for a total
AP Biology Chapter Summary
1515 Words | 7 PagesBiology, the study of life and living organisms, is complex and encompasses a multitude of theories and ideas. In AP Biology, the first unit covered was evolution. Chapters 29, 31, 39, 40, 41, 42, and 43 in the textbook, Campbell’s Biology in Focus, not only discusses the four main ideas of biology: evolution, energy, information, and systems, but it also gives examples of each in order to help guide the reader’s understanding of the concepts. The first big idea of AP Biology is: “the process of evolution drives the diversity and unity of life.” Chapter 39 in the textbook encompasses this main idea through discussing natural selection and genetic diversity.

Explain The Organs Involved In The Homeostatic System
908 Words | 4 PagesQ1 The organs involved in the homeostatic system of salt regulation are pineal gland, pituitary glands, thyroid gland ,thymus, adrenal, pancreas, ovary and testis. All our bodies removes uneeded fluid by filtering your blood through your kidney, via osmosis, to draw excess water out of your blood. This requires a balance of sodium and potassium to pull the water across the wall from the bloodstream into a collecting channel in the kidney. A high salt diet will alter this sodium balance, causing the kidneys to have reduced function and remove less water resulting in higher blood pressure.
Summary Of Gulp By Mary Roach
1777 Words | 8 PagesMary Roach dives into the world of science and biology throughout the novel, Gulp, and explains it particularly in reference to the alimentary canal. She starts at the beginning with simply how eating works when it comes to taste preferences. Since humans tend to “taste” through their noses, the act of eating is actually more of an olfactory experience, surprisingly enough. Next, the food must travel past the saliva which carries digestive enzymes and kills proteins in order for the food to get to the stomach. The gastric acid within the stomach then breaks down the food and sends it to be filtered back out through the anus.
Resting Membrane Potential Lab Report
1566 Words | 7 PagesThe negatively charged protein molecules (A-) inside the neuron cannot cross the membrane. In integration to these selective ion channels, there is a pump that utilizes energy to move three sodium ions out of the neuron for every two potassium ions it inserts. Conclusively, when all these forces balance out, and the difference in the voltage between the inside and outside of the neuron is quantified, have the resting membrane potential. The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this designates that the inside of the neuron is 70 mV
Compare And Contrast The Equilibrium Potential Of Chloride Ions Diffuse Into The Cell
192 Words | 1 Pages1. Chloride ions will diffuse into the cell, as it is moving from an area of high concentration, to an area of low concentration. Chloride ions will diffuse into the cell because the equilibrium potential of chloride ions is more negative than the membrane potential, therefore when chloride ions diffuse into the cell the equilibrium potential of chloride ions and the membrane potential will become more balance. If, by the process of active transport, chloride ions moved out of the cell this would create a bigger gap between the equilibrium potential of chloride ions and the membrane potential. 2.
Tubular Reabsorption Essay
1295 Words | 6 PagesName: Sarah Trudel Student Number: 5973771 1.Describe the process of water, nutrient and electrolyte reabsorption in the nephron of the kidney. In your answer, make sure to address the following questions: (11 marks total) a) What molecules are reabsorbed in each tubular element of the nephron? (7 marks) Tubular reabsorption is the process of reclaiming water and solutes from the tubular fluid and returning them to the blood (Saladin, 2004). The first part of the nephron that is involved in the tubular reabsorption is the proximal convoluted tubule (PCT) (Silverthorn et al., 2013). Once the glomerular filtrate reaches the PCT, the following molecules are reabsorbed: Water (H2O), Sodium chloride (NaCl), bicarbonate ions (HCO3-), Calcium
Cellular Respiration Research Paper
1393 Words | 6 PagesCellular Respiration One of the main essentials of life that all organisms need in order to function in our world is, energy. We receive that energy from the food that we eat. Cellular respiration is the most efficient way for a cell to receive the energy stored in food. In cellular respiration, a catabolic pathway, which breaks down the molecules into smaller units, in order to produce adenosine triphosphate, also known as, ATP. ATP, is used by cells in the act of regular cellular operations, it is a “high energy” molecule.
Compare And Contrast Cellular Respiration And Photosynthesis
420 Words | 2 PagesIn cellular respiration, chemical energy that comes from fuel molecules is converted into ADP. ADP join with phosphate, then converts into ATP to form energy currency of cells. Cells release phosphate after consuming the ATP, which join with ADP to renew the cycle. The cycle state is called the glycolysis, electron transport and the acid cycle. They both provide energy that is used by plants, and recycle each other's "waste" for
Sodium Homeostasis
562 Words | 3 PagesTo avoid these extremes, the body has developed an entire hormonal axis devoted exclusively to sodium homeostasis. The kidney is the primary organ dedicated to sodium homeostasis; in most scenarios this means sodium retention. Between the glomeruli and distal convoluted tubule (DCT) in each nephron, a sensor called the juxtaglomerular apparatus (JGA) measures the flow rate
Mandatory Synthesis Essay

These are digested by organs, and through the electron transportation, it is changed as ATP. This substance is important for cell as an energy resource. According
Hodgkin-Huxley Model Essay
895 Words | 4 PagesSince equilibrium cannot be reached, an electrochemical driving force is generated which acts on the ions. It is derived by finding the difference between the membrane potential obtained and the equilibrium potential expected. The sign of the value of this force decides the direction of movement of ions. Since we have cations (positive ions), a positive value shows movement of ions outside the cell membrane and a negative value shows movement of ions inside the cell membrane. If the value is equal to that of the equilibrium potential, the driving force acting on the ion is 0.
Carrier Protein Research Paper
729 Words | 3 PagesGlucose transporter 1 (GLUT1) is a kind of carrier protein responsible for the passage of glucose across the plasma membrane through facilitated diffusion or active transport. If the extracellular concentration is greater than the intracellular one, the glucose have to be mediated by carrier proteins for diffusion owing to the polar nature. Otherwise, the glucose will be transported by active transport. Being an important source of energy for human body, glucose is to maintain cellular respiration, which helps the synthesis of ATP, an energy source for primary active transport, such as the Na-K-ATPase.
