The only part of a triglyceride that can be used to make glucose (via gluconeogenesis) is the glycerol backbone.

A triglyceride is a type of fat. It consists of a glycerol backbone and three fatty acids attached to each of the hydroxyl group of the glycerol. High quantities of triglyceride can be harmful for the body, especially the heart. The normal range of triglycerides in the body should be less than 150 mg/dL.

Glycerol is a three carbon structure consisting of three hydroxyl groups attached to each carbon. It is of great importance for living organisms as it forms the backbone for various phospholipids and other lipid structures.

alina1380 [7]

At the monastery of San Marco, Fra Angelico and his assistants frescoed paintings in the cells of the monks and their community rooms. The monastery of San Marco is a convent in the Italian city of Florence. The monastery was reconstructed in its current state in 1437, while the decorations of the walls started in 1439. The decorations were carried out by Fra Angelico (or officially named Giovanni of Fiesole) and his assistants. The frescoes he painted are said to prove his respect for his god and his love for humanity.

What happens in cellular respiration if there is no oxygen?

Alex

If there is no oxygen...many cells die....but some can perform cellular respiration without oxygen too.....they are anaerobic. they usually use organic substance to survive !!!

as acidophilic bacteria survive without oxygen in acids ...so !!!

Tatiana [17]

The experimental process of determining the relative location of genes or other segments of DNA along individual chromosomes is called Genome mapping or chromosome mapping.

Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).

Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.

Under aerobic conditions, when is pyruvate produced and consumed? It is produced in glycolysis and consumed in fermentation.It i

Nastasia [14]

1. The correct answer is: It is produced in glycolysis and consumed in the citric acid cycle

Pyruvate is a molecule that connects metabolic processes of cellular respiration: glycolysis and Krebs (citric acid) cycle. Glycolysis is a process that occurs in the cytosol of the cell and in which several of enzymes catalyze the breakdown of glucose molecules. At the end of glycolysis, products are two pyruvate molecules and released energy (ATP).

After this step, in the matrix of mitochondria oxidation of pyruvate occurs. During this reaction, pyruvate is converted into a three-carbon molecule—acetyl CoA. Acetyl then acts as fuel for the citric acid cycle.

2. The correct answer is: electron transport chain

The amount of ATP produced per glucose is:

Glycolysis: 2 ATP

A process in which glucose is converted into two molecules of pyruvate, ATP is made, NAD+ is converted into NADH.

Krebs Cycle (citric acid cycle): 2 ATP

The acetyl CoA (made from pyruvate) goes through a cycle of reactions. ATP, NADH, FADH2 and CO2 is released.

Electron Transport Chain (oxidative phosphorylation): 28 ATP

Electrons from NADH and FADH2 move down the electron transport chain, protons are pumped out of the matrix, forming a gradient. Gradient of proton is used for the ATP synthesis.

Fermentation: 2 ATP

Breaking down carbohydrates (usually glucose) in the absence of oxygen.
