Living organisms use energy from the metabolism of food to create an energy rich molecule called adenosine triphoshpate (ATP). the ATP then acrs as and energy source for a variegty of reactions that the living organism must carry oyut to survive. ATP provides energy through its hydrolysis, which can be symbolized as follows: ATP(aq)+H2O(l) --> ADP(aq)+Pi(aq) with a delta G of the reaction being =-30.5 kj. Where ADP represents adenosine diphosphate and Pi represents in inorganic phosphate group (such as...

3. (4 pts) Living organisms use energy from the metabolism of food to create an energy-rich molecule called adenosine triphosphate (ATP). The ATP then acts as an energy source for a variety of reactions that in living organisms must carry out to survive. ATP provides energy through its hydrolysis, which can be symbolized as follows: ATP(aq) + H2O(l) → ADP(aq) + Pin(aq) &Gorun =-30.5 kJ where ADP represents adenosine diphosphate and Pm represents an inorganic phosphate group (e.g., HPO,). In...

The essential requirements to maintain a living unit like the first cell are: organic energy sources; an information storage system; an expression system that uses the information to both exploit energy sources and to reproduce; and a method of containment to distinguish the living cell from the outside world. For each of the last three categories, identify the key molecules or groups of molecules used by the first cells that allowed them to maintain and propagate, and describe the properties/characteristics...

1) One of these statements is incorrect. Which one? Group of answer choices Energy is the capacity to do work or transfer heat. Exothermic processes transfer heat from the surroundings into the system. Endothermic processes have a positive ΔH value. Energy is neither created nor destroyed in chemical reactions. 2) Choose the compound from the set that can be classified as a salt. Group of answer choices sodium hydroxide (NaOH) acetic acid (CH3CO2H) glucose (C6H12O6) magnesium bromide (MgBr2) 3) Which...
