1.Energy is stored as stored chemical energy in the bonds between phosphate groups in the ATP molecules. When ATP is hydrolyzed and the bonds between phosphates are broken, the energy is released.

2.ATP can power cellular processes by transferring a phosphate group to another molecule. This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.

4.Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2. Carbon dioxide + water + energy from light produces glucose and oxygen.

Explanation:

The given statement is true.

Explanation:

The chemical structure of triglycerides includes:A glycerol molecule attached with ester bonds to,Three fatty acid chains.Among all the bio-molecules available in the cells, triglycerides store the maximum energy, due to the presence of long carbon chains with single (saturated) or double/triple (unsaturated) bonds.One gram of triglyceride can store about 38 kJ of energy which is double the amount that can be stored in carbohydrates.During metabolism, these molecules are hydrolysed by enzymes called lipases, those are secreted by the pancreas, into fatty acids, mono- and di-glycerides, by the process of lipolysis.Bile in the intestine further promotes the action of lipases.These digested components are absorbed into the duodenum through the enterocyte cells where they associate with proteins and cholesterol to form chylomicrons.These chylomicrons are released into the lymphatic system and from there cells of various organs can absorb them for storage or hydrolysis.The triglycerides are used in the cells for energy by hydrolysing them using cell specific lipases to fatty acid and glycerol.The glycerol is used to produce glucose and the fatty acids are further hydrolysed or converted to ketone from which amino acids can be formed.
