Glycerol has 3 OH groups and a fatty acid has one carboxyl group. One mole of Glycerol reacts with 3 moles of fatty acid to give 3 moles of water and one of the glycerine tri-ester - more commonly called a triglceride.

What do you mean by building blocks?
amino acids are the building blocks of proteins. when many amino acids bind with each other chemically, a peptide bonds is formed.
What does Carbon dioxide bind to in the Calvin cycle?
Carbon dioxide acts as a source of carbon, it is an inorganic molecule which reactions with RuBP (Ribulose 1,5 bisphosphate) to for an unstable 6 carbon compound which breaks down into 2 molecules of GP (Glycerate 3-phosphate). Note: The reaction of CO2 and RuBP is catalysed by Rubisco (Ribulose 1,5 bisphosphate carboxylase oxygenase) GP in turn is used to synthesize amino acids (with the use of nitrates from the soil) and fatty acids.
Plasma membrane in eukaryotic celss is made up of?
The plasma membrane in a eukaryotic cell has several major components: phospholipids, embedded proteins and other lipids such as cholesterol. Phospholipids are the primary component of plasma membranes. They consist of a glycerol base with one bound phosphate group (which is highly polarised, that is the charge density of the electrons is not distributed evenly; we call this hydrophilic because it attracts water) and 2 fatty acid chains attached. The fatty acid chains are not very polarised because they are strings of carbon and hydrogen bound to the glycerol as an ester (if you don't know what this is, don't worry). What is important is the fatty acids are hydrophobic - because they are not polarised they don't attract water and interact much more easily with less polar molecules (like each other). The phospholipids arrange themselves in a bilayer, with the lipid tails pointing in to the middle and interacting weakly with each other, while the phosphates sit on the outside of the glycerol molecule and interact with the water. This is the basis of the plasma membrane. Additionally, the plasma membrane contains lots of embedded proteins. These proteins all contain a hydrophobic domain, normally a repeating sequence of hydrophobic amino acids that doesn't attract water and quite happily interacts weakly with the fatty acid tails. The other ends of the protein normally do something useful like bind to chemical signals and change shape, to pass on the message to the inside of the cell that the chemical signal is outside. Others help anchor the cell to something outside. Plasma membranes also contain other lipids such as cholesterol which have a specific shape and help to give the membrane certain structural properties.
What is the function of protease?
To bind into to target sequences of the proteins, split them into to polypeptide chains or amino acids. So, to say simply, it degrades protein. An example to it is Pepsin.
What makes egg whites a good buffer?
Protein in egg whites is composed of amino acids. These amino acids can accept and donate hydrogen ions, which makes the protein an excellent buffer.
How are organic molecules such as glucose fatty acids and amino acids used by glycolysis and Kreb's cycle to produce usable energy?
the bonds that hold the molecule together are broken and used to bind a phosphate to ADP creating ATP.
What kind of food reacts with the enzymes?
well every food reacts with enzymes, almost at least. for example carbohydrates such as startch , digest in to maltose by means of salivary amylase in the saliva, and amylase from the pancreas. and then the enzyme maltase helps digest maltose into glucose. and so on. in protein , HCl bind with pepsin to produce the enzyme pepsinogen which then brakes down long chains of amino acids into shorter ones, and other enzymes help digest these amino acids into even smaller ones. and also fats, get broke down by lipase, breaking it down to glycerol, and three fatty acids
What do the ribosomes create?
rRNA and associated proteins creates ribosomes.
Would you find hydrophillic or hydrophobic amino acids on the external surface of a protein a protein?
Hydrophobic amino acids would be on the external surface of a protein. This is because these are the types of amino acids that help bind things together.
What do you mean by building blocks?
amino acids are the building blocks of proteins. when many amino acids bind with each other chemically, a peptide bonds is formed.
What happens to the two amino acids carried by the two tRNA's inside a ribosome?
The two amino acids carried by the two tRNA's inside a ribosome, bind togather with a peptide bond to elongate the protein chain.

What small molecules bind to hemoglobin?
Carbon dioxide and BPG bind to amino acids located on hemoglobin. Oxygen molecules bind to the iron molecules located in the heme. Each hemoglobin molecule can carry up to four oxygen molecules, one on each of the four iron molecules. Nitric oxide can also bind to hemoglobin when either oxygen or carbon dioxide are bound to the hemoglobin.

Compounds commonly know as fats and oils?
Fats and oils are categorized under the title "Omega", followed by varying numbers (Omega 3, Omega 6,) some are very benifitial to the cognitive areas of the brain, aiding in memory retention, and strengthening the immune system. Some types of fat are actually harmful to the human brain and body functions when ingested in large amounts, such as corn oil. Helpful forms of Omega can be found in fish like salmon, nuts, and coconut oil.
Why ribosomes make protein?
Ribosomes are protein factory that synthesize proteins from amino acids (no other organelle can do this). Ribosomes structures containing site for protein production. when the mRNA exported to cytoplasm, ribosomes sense it and bind to start protein synthesis.
What is the relationship between the order of bases in DNA and the order of amino acids in the final protein?
Amino acids are fundamental in your DNA. You need them to make DNA. You need them to be alive. Amino acids bind together in a special combination that your body needs to make more.
