BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

TWO-PARENT BABIES WILL NOT BE ENOUGH IN THE NEAR FUTURE Yes‚ you read that right five years from now‚ the little kid that you’ve been babysitting will draw four people in the wall saying that those are his/her parents‚ pointing at the three people behind him/her. You might probably think that his dad/mom had an affair and the kid is too young to know about this stuff or you might ask yourself “why?” and “how did that happen?” but nothing’s impossible now – especially when you deal with science!

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process that breaks down food to use as energy. The three main stages are glycolysis‚ citric acid cycle‚ and electron transport (Simon‚ Reece‚ & Dickey‚ 2010). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? During glycolysis‚ a team

Mitochondrial Diseases are very diverse. Specialized organelles in every cell of the body (only red blood cells lack mitochondria). Mitochondria generate more than 90% of the energy required by the body. Mitochondrial dysfunction depletes cells of energy causing cell damage and even cell death. Due to the high energy requirements of brain and muscle‚ mitochondrial disease typically affect these parts of the body causing Brain and Muscle disease. Other organs are frequently affected including: eye

Biochemistry GRT1 Task 4: Metabolism Enzyme Induced Fit Model and Activation Energy Role of Enzymes: Enzymes are proteins that act as catalysts during a biochemical process. Catalysts are non-changing enzymes that can increase or decrease activation energy to accelerate or slow down a biochemical reaction without using additional energy. Enzymes break down molecules in our body faster than they would normally break down without enzymes. On the biochemical level‚ enzymes work at precise

“Common biochemical themes are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell
