Hi guys so I’m a little confused on energy transfers which take place in living organisms.
Am I right in saying this: Plants use light energy from the sun and convert this into chemical energy via photosynthesis. This chemical energy is used via respiration for the production of the energy carrying molecule ATP. Therefore the energy has been transformed from chemical to an immediate source of energy ATP which is the energy currency for cells. ATP splits into ADP + pI which releases energy for the process of active transport of sodium ions into the xylem which causes water to move out of the endodermis into the xylem down its water potential gradient that has been caused by the energy of active transport supplied by ATP of sodium ions into the xylem. This therefore transfers the energy into kinetic energy in the form of movment of water and the sodium ion carrier protein on the CSM of the endodermis.
In addition to this would it also be right in saying that as consumers/animals feed on producers it transfers the chemical energy which organisms can then use for the process of respiration=ATP. ATP then used for muscle contraction=transfers energy into kinetic + heat from movement (and metabolic heat???)
Also ATP splitting gives ADP + pI and hence releases energy. If you say as ATP attaches to a carrier protein such as (NA K pump) and sodium ions attach to receptor sites in the sodium potassium pump ATP splits into ADP +pI (remaining attached to carrier protein) but releases energy for the sodium potassium pump to change shape…IS THIS A TRANSFER OF ENERGY I.E. ATP ENERGY =RELEASE ENERGY=KINETIC ENERGY FOR MOVMENT OF MOLECULES AGAINST CONCENTRATION GRADIENT AND THE FACTOR THE CARRIER PROTEIN CHANGES SHAPE?? ALSO DOES THIS RELEASE HEAT energy??
Also what’s all this talk about metabolic heat/metabolic rate/metabolism?
Is everything with metabolism talking about glucose + oxygen=CO2 +H20 and hence the production of the energy carrying molecule ATP that therefore somehow creates heat? So am I right in saying everytime the ATP molecule produced energy in the form of chemical is transferred into heat energy and ATP as an energy soruce???
