2 ATP + 4 ATP = + 2 ATP. So does this solve the direction problem? Only for a second … Where does this ATP come from, if we are E. coli growing in minimal medium… Glucose is the only carbon source. Need to make ATP from glucose, and this TAKES energy. Need only to regenerate ATP from ADP:.
ATP. Controlled Energy Flow. What is the safest way to get out of a building 5 story building? Walking down stairs Jumping out the window Why?. Controlled Energy Flow. What is the safest way to get out of a 5 story building? Walking down stairs Jumping out the window.
ATP. Adenosine triphosphate- the principal chemical compound that cells use to store and release energy. Consists of adenine, Ribose, and three phosphate groups. ADP - adenosine diphosphate, it looks like ATP but has two phosphates instead of three.
ATP?. Depends on the system…. 1 ATP – Glucose to G-6-P Ribose-5-P 1 ATP – But 2 high energy bonds to get to PRPP 4 ATP – In vertebrates to get onto IMP from PRPP 5 ATP – In prokaryotes to get onto IMP from PRPP
Making energy!. ATP. The point is to make ATP !. Chemical energy. (a). First law of thermodynamics: Energy can be transferred or transformed but Neither created nor destroyed. For example, the chemical (potential) energy in food will be converted to the kinetic
ATP. The Energy Currency of Living Organisms. Objectives. Understand the molecule ATP. Expected outcome. Describe the structure of ATP Explain how ATP is broken down and synthesised Explain why ATP is known as the universal energy currency. Why do organisms need energy?.
Making energy!. ATP. The point is to make ATP !. The energy needs of life. Organisms are endergonic systems What do we need energy for? synthesis building biomolecules reproduction movement active transport temperature regulation. Where do we get the energy from?.
ATP. 1. Receptor Protein recieves Hormone 2. Hormone goes in 3. Transport vesicle floats 4. Hormone calls for info to be copied. 5. DNA copied to RNA 6. RNA leaves into the ER. 7. Ribosome reads RNA and builds Protein 8. Vesicle leaves ER for
