Answer:
Eukaryotic cells make energy-rich molecules such as ATP and NADH through energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation, beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules.
Explanation:
Used for energy by mammals
Answer:
A. Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
Explanation:
Energy, as stated in this question, can be of two types namely: kinetic energy and potential energy. Kinetic energy is the energy due to motion i.e the energy used to transport solute etc.
On the other hand, potential energy is the energy due to position like the energy stored in the covalent bonds of a molecule. Based on this question, the fact that triglycerides (a type of lipid) store about twice as much energy as polysaccharides (carbohydrate) is evidence that POTENTIAL ENERGY is stored in covalent bonds.
