Admin Is DNA the energy carrier for the cell?
Explanation: It is an important molecule that carries energy to the cells. It is made of nitrogen base, ribose sugar and three phosphate groups.
Is NADH an energy carrier?
NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
Why is ATP an energy carrier?
ATP captures the chemical energy released by the combustion of nutrients and transfers it to reactions that require energy, e.g. the building up of cell components, muscle contraction, transmission of nerve messages and many other functions. …
What molecules are energy carriers?
Two of the most important energy-carrying molecules are glucose and ATP (adenosine triphosphate). These are nearly universal fuels throughout the living world and both are also key players in photosynthesis.
How is energy obtained by the cells of our body for Class 7?
The energy that is required by our body is obtained by breaking down of glucose in the cells by the help of oxygen. The unabsorbed and undigested food passes into large intestine.
Is hydrogen an energy carrier or energy source?
Energy Carrier. Hydrogen is an energy carrier, not an energy source and can deliver or store a tremendous amount of energy. Hydrogen can be used in fuel cells to generate electricity, or power and heat.
What are the characteristics of energy carriers?
Energy carriers vary on multiple dimensions (e.g. volumetric energy density, gravimetric energy density, ease of storage, ease of transport, cleanliness) and they are only partially substitutable (e.g. try running a truck on battery-stored electricity). Patrik Thollander, Jakob Rosenqvist, in Introduction to Industrial Energy Efficiency, 2020
Can energy carriers be produced as by-products?
In another case an energy carrier produced as a by-product can be treated as an individual fuel (e.g. blast-furnace gas. In some cases the production of energy carriers must be supplemented by external supplies (e.g. electric energy).
What does it mean for an energy carrier to have 100% exergy?
An energy carrier3 with 100% exergy corresponds to a 100% possibility of converting the energy carrier into mechanical work. Exergy yield per mass unit can be obtained from Eq. (2.17).
