Vocabulary words II: 1. Closed system - a region that is isolated from its surroundings by a boundary that admits no transfer of matter or energy across it 2. Undefined media - basal or complex media 3. Z-streak - is a technique used to isolate a pure strain from a single species of microorganism‚ often bacteria 4. Selective media – a growth medium or culture medium is a liquid or gel designed to support the growth of microorganisms or cells‚ or small plant 5. Differential media -are

Chapter 6 Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained in a molecule’s chemical bonds‚ called enthalpy.* TS: the energy term related to the degree of disorder in the system. T is the absolute temperature (K)‚ and S is the entropy.We can use the change in free energy to predict whether

Biology‚ is the study of living things. In biology there are many branches that all contribute to life. Those branches of life aid each other’s function to maintain their function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

Each small group has to designate a leader. Each
Premium Cellular respiration Metabolism Photosynthesis
Energy levels are lost as the electron travels down the transport chain. Some of the energy which is lost is released into H+ ions from the stroma into the interior of the thylakoid. As the H+ ions flow through the gradient to reach to the stroma. Chemiosmosis occurs which is when the Atp synthase is driving the Atp production

This tutorial focused on the final steps of cellular respiration; the Krebs cycle and the Electron Transport Chain and chemiosmosis. Recall that at the end of glycolysis there is a net production of two molecules of ATP and two molecules of NADH. The ATP is produced via substrate-level phosphorylation; in this reaction‚ a phosphate group on an organic molecule is transferred
