essential
can the essential amino acids be made from glucose
An amino acid is considered essential if the human body cannot synthesize it in sufficient amounts. Therefore, essential amino acids must be obtained through the diet to support proper growth, maintenance, and repair of the body's tissues.
heterotrophs
Leucine is an essential amino acid, meaning it must be obtained through diet as the body cannot produce it. Lecithin and linoleic acid are not amino acids, they are fats. Aspartic acid is a non-essential amino acid, meaning the body can synthesize it.
Yes, glycine, alanine, and serine are all nonessential amino acids, meaning our bodies can typically synthesize them on their own. Essential amino acids are the ones that must be obtained through diet because the body cannot produce them.
They are grown on medium that contains the nutrient that they cannot synthesize
No. In humans there are nine essential amino acids that cannot be synthesized by the human body, and which humans must get in their diet. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histadine. Other animals may have a different set of essential amino acids.

Plants that lack chloroplasts cannot synthesize simple sugars via photosynthesis. Chlorophyll is essential in absorbing light energy that converts water and carbon dioxide to simple sugars. Oxygen is emitted in the process
One common chemical used in cat food is taurine, with the chemical formula C2H7NO3S. Taurine is essential for cats as they cannot synthesize it themselves and must obtain it from their diet.
Heterotrophs
They cannot synthesize own food. photosynthesis gives food for them
