What molecules does a fat cell store

mafiozo [28]

Answer:

Triglycerides

Explanation:

Fat cells are also called Adipose cells. They are cells found all over the body and majorly functions in the storage of energy storing substances called TRIGLYCERIDES. Triglycerides are a type of lipids composed of a glycerol molecule and three fatty acids molecules.

Triglycerides, like every other lipid, are biomolecules that store a large amount of energy. However, they are stored in specialized cells called FAT OR ADIPOSE CELLS.

Suggest appropriate sources of food to meet their requirements for a Newborn baby and child aged 6.

pashok25 [27]

Explanation:

Calcium . Helps build strong bones and teeth.

Fat. Creates energy, helps the brain develop, keeps skin and hair healthy, and protects against infections.

Folate. Helps cells divide.

Iron. Builds blood cells, and helps the brain develop. Breast-fed babies should receive iron supplements.

Protein and carbohydrates. They provide energy and fuel growth.

Zinc. Helps the cells grow and repair themselves

Your baby also needs vitamins such as:

Vitamin A. Keeps skin, hair, vision, and the immune system healthy.

Vitamin B1 (thiamine). Helps the body turn food into energy.

Vitamin B2 (riboflavin). Helps the body turn food into energy, and protects cells from damage.

Vitamin B3 (niacin). Helps the body turn food into energy and use fats and protein.

Vitamin B6. Keeps the brain and immune system healthy.

Vitamin B12. Keeps nerve and blood cells healthy, and makes DNA -- the genetic material in every cell.

Vitamin C. Protects against infections, builds bones and muscles, and helps wounds heal.

Vitamin D. Helps the body absorb calcium from food, and keeps bones and teeth healthy. Breast-fed babies may need a D supplement.

Vitamin E. Protects cells from damage, and strengthens the immune system.

Vitamin K. Helps the blood to clot.

LuckyWell [14K]

Answer: Daughter cell that does not receive mitochondria, will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria, will be able to carry out cellular respiration and thus produce energy.

Explanation:

The mitochondrion is a cellular organelle found in eukaryotic cells, and provides the energy needed to carry out cellular activity. They are characterized by their large size, compared to other cell organelles, and their globular shape. Mitochondria generate most of the chemical energy needed to activate the biochemical reactions in the cell, through a process called cellular respiration. It irefers to a set of biochemical reactions by which certain organic compounds are degraded by oxidation into inorganic substances. The chemical energy produced by mitochondria is stored in an energized molecule called adenosine triphosphate (ATP).

Then, if during cell division, one of the daughter cells does not receive mitochondria, it will not have the necessary organelles to carry out cell respiration and will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria will have no major problems, it will be able to carry out cellular respiration and thus produce energy.
