Answer:
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.
Answer:
Evidence: Your hands begin to heat up, and may begin to feel warmer and no longer cold.
Explanation:
When you hold your hands near a fire, pull them away and touch someone, they may exclaim in shock at the heat. Your nerves would also alert you if your hands begin to get to hot, they may even start to sweat as an effect.

Answer:
c) The membrane phospholipids of cold-adapted organisms will have more unsaturated hydrocarbon tails
Explanation:
The cell membranes are fluid, the lipids that compose it have some movement. In cold temperatures that movement is reduced and the membrane becomes more rigid. To overcome this, organisms that live in cold environments have certain adaptations that keep the membrane fluid.
One of those adaptations is to contain more unsaturated phospholipids. Unsaturated phospholipids contain double bonds that introduce “kinks” in the hydrocarbon tails, which interfere with the lipid's packing and reduce rigidity.
