The right answer is more Chemical bonds.
Lipids are the most energetic macronutrients (as a reminder: 1 g of lipids represents 9 kcal, against 4 kcal for 1 g of carbohydrates or 1 g of proteins). Lipids are the molecules present in the fat of foods. They divide into saturated fatty acids and unsaturated fatty acids. These fatty acids can contain between 4 and 20 carbon molecules while carbohydrates contain between 3 and 6 carbon molecules.
only animals have a cell membrane
Answer:
Glycocalyx
Explanation:
Glycocalyx is carbohydrate rich (glycoprotein + glycolipid) coating that is found in outer surface of cell membrane of many prokaryotic and eukaryotic cells specially bacteria.
Glycoprotein=Carbohydrate + Protein
Glycolipids= Carbohydrate + Lipids
Glycocalyx provied a barrier between cell and its surrounding, adhesion and provide protection in bacteria. In eukaryotes it can be used to identify cells.
