Membrane Structure

How is the membrane structure related to the transport of materials across the membrane? The membrane structure plays an important role in the transportation of materials across the membrane. The Cell membrane is a barrier that separates a cell from its surrounding environment. This is composed of Phospholipids, Proteins, Cholesterol and Carbohydrates. The Membrane Structure has a very important role in the transportation of materials across the membrane. The membrane of the cell is made up of phospholipids. Those phospholipids have hydrophilic heads and hydrophobic tails. Hydrophilic heads mean they are able to interact with water.

In the transport across the membrane Molecules move from areas of high concentration, to areas of low concentration. …show more content…
According to biologypages.com, the process of cellular respiration occurs in two glycolysis and the complete oxidation of pyruvate acid to carbon dioxide and water. Glycolysis breaks down glucose and forms pyruvate with the production of two molecules of ATP. The pyruvate end product of glycolysis can be used in either anaerobic respiration if no oxygen is available or in aerobic respiration in the TCA cycle in which has much more energy being able to use for the cell. After Glycolysis the cell goes through link reaction which forms an important link between the metabolic pathways of glycolysis and the Citric Acid cycle. Next comes the Krebs cycle. The Krebs cycle comes after the link reaction providing the hydrogen and electrons needed for the electron transport chain. This process takes place strictly the Mitochondria. Following the Krebs cycle, happens the the electron transport chain. The electron transport chain in the mitochondria is the site of oxidation phosphorylation. The NADH and succinate generated in the citric acid cycle are oxidized to provide energy to power ATP
