5 - Myosin is an enzyme that can convert chemical energy into mechanical energy. In what form is the chemical energy stored? In what form does the mechanical energy get expressed? Illustrate in a four-step drawing how the chemical energy is converted to mechanical energy.
Myosins are motor proteins that have ATPase activity. Myosins
help in the movement of actin filament by utilising energy released
after ATP hydrolysis. Conversion of chemical energy of the ATP
molecules into mechanical energy by the myosins help in muscle
contraction during movement.
Myosin molecules are composed of head, neck and tail domains.
Myosin head has the ATPase activity and during muscle contraction
myosin head binds to the actin filament and ATP. Energy from the
ATP hydrolysis helps in the bending of myosin head and provide the
force to walk along the actin filament.

000000 5. Some bacteria make an enzyme that can convert dihydroxyacetone to dihydroxyacetone phosphate (DHAP). How would this help these cells yield energy? Hint: look at the diagram of glycolysis to the right Glucose Ister Unstable 0000000- Fructose-1,6-bisphosphat DHAP glyceroldehyde- • 3-phosphate - -- - - - - - All the DHAP MAD, will be converted into gyaraldehyde RAM 3-phosphate ADP Happens Pyruvate 6. If a cell respiring on glucose runs out of oxygen and/or other electron acceptors, what happens...
What is the purpose of photosynthesis? Question 5 options: It produces a form of chemical energy that the plant can use as needed It allows plants to remove excess NO2 from the atmosphere Plants do it to produce oxygen so animals and humans can breathe It is a way for producers and consumers to release the energy stored in sugar molecules
A. Food Energy. Energy is stored in food as the potential energy of the electrical bonds in molecules. Your body converts food energy to mechanical energy and heat. Food energy is expressed in “calories”, which are actually kilocalories (kcal, with 1 kcal= 4.185 kJ) How many joules are in a 130-kcal serving of breakfast cereal? B. A glass of 1 percent milk contains 130 kcal. How many glasses would a 70-kg person have to drink to get the energy needed...
Alternating current (AC) machines are generators that convert mechanical energy to AC electrical energy and motors that convert AC electrical energy to mechanical energy. The AC machine are categorized as synchronous machine and induction machine. (Mesin-mesin arus wlang-alik (AU) adalah penjana-penjana yang memukarkan tenaga mekanikal kepada tenaga elektrik AU dan motor-motor xang memukarkanm tenaga elektrik AU kepada tenaga mekanikal Mesin AU dikategorikan kepada mesin segerak dan mesin aruhan (ii) rotor frequency,f frekuensi pemtar,1 (1 Mark/ Markah) (iii) stator copper losses,...
