The rigid layers of fungal cell walls contain polysaccharides called chitin and glucans. The wall protects the fungus from desiccation and predators. Most fungal hyphae are divided into separate cells by endwalls called septa(e). These tiny holes in the septa allow the rapid flow of nutrients and small molecules from cell to cell along the hypha.
Answer:
Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
This cell city represents plant cell due to the presence of chloroplast.
<h3>What represents each part of the city?</h3>
In the cell city, the power plant represents mitochondria due to its production of energy. The storage tanks represent vacuoles because in cells in vacuoles materials are stored.
The transport company represents Golgi apparatus which also transport material within the cell, city hall represents nucleus because all the activities can be controlled from here.
The waste disposal plant represents Lysosomes because it removes waste. The construction site represents Ribosomes and Endoplasm Reticulum where proteins are produced. The food processing company represents Chloroplasts.
"Cell City" represent an plant cell because it has chloroplast which is only present in plant cell.

Answer:
Glycerol+fatty acid=triacylglycerol+water
Explanation:
The above reaction is termed as lipogenesis which helps in the synthesis of triacylglycerol from glycerol 3 phosphate by various enzyme catalyzed steps.
In general the OH part of -COOH group of fatty acid attacks the hydroxyl group of glycerol resulting in the formation of fatty acid ester of glycerol (triacylglycerol) and water is eliminated as a byproduct of this reaction.
