respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further oxidized in the mitochondria. Each mitochondrion is enclosed by two membranes separated by an intermembrane space. The intermembrane space extends into the folds of the inner membrane called cristae which dramatically increase the surface area of the inner membrane. Cristae extend into a dense material called the matrix‚ an area which contains RNA‚ DNA‚ proteins‚ ribosomes and range of solutes. This is similar to

Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This

are many pros and cons to the war in Iraq and sending troops to the Middle East‚ but what if our government took a different approach? What if they took the time to investigate the origin and root causes of their attack? Our government took little time and lesser thought to do so and in order to reach the root causes of Islamic terrorism; we must rely on history and current

To investigate the effect of different caffeine concentration on the heartbeat rate of Daphnia at room temperature. Introduction: Caffeine is found‚ and produced in many plant species to function as a natural pesticide‚ and as an inhibitor of seed germination of other nearby coffee seedlings to give it a better chance of survival. Caffeine is able to paralyze and kill certain insects upon feeding on the plants that produce caffeine. Coffee‚ tea and cocoa are common caffeine-containing

electrically excitable membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement of ions across the membrane will changes the membrane potential. In the

“Finding Your Roots” We‚ people are related species that have lot of things in common. We all originated from a same ancestor Homo sapiens who were mutual parents in the past. When we compare one another genetically‚ we both possess 99.9% of genome sequence identical. It depicts that we all originated from a same blood and entirely related to one another. If we track our ancestors‚ long way behind we will find the same parents in our genome identity. Miraculously‚ the remaining one tenth of the
