Carbohydrates lipids proteins nucleic acids step by step

What are carbohydrates?

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen. They provide energy and structure in biological systems.

Function of lipids?

Lipids store energy, provide insulation, and make up cell membranes. They are hydrophobic molecules.

Proteins are made of?

Proteins are polymers made of amino acids linked by peptide bonds. They perform a wide variety of functions.

What is the role of nucleic acids?

Nucleic acids, like DNA and RNA, store and transmit genetic information.

Difference between saturated and unsaturated fats

Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.

Fill in the blank: Amino acids are the building blocks of ______.

Proteins.

True or false: Carbohydrates are hydrophobic.

False, because carbohydrates are hydrophilic due to their polar hydroxyl groups.

What are monosaccharides?

Monosaccharides are the simplest form of carbohydrates, including glucose and fructose.

Question: What is a triglyceride?

A triglyceride is a type of lipid formed from glycerol and three fatty acids.

List two functions of proteins.

- Enzymatic activity - Structural support

Fill in the blank: _______ is the primary energy source for cells.

Glucose.

True or false: DNA is a type of protein.

False, because DNA is a nucleic acid.

What is the structure of a nucleotide?

A nucleotide consists of a sugar, phosphate group, and nitrogenous base.

Difference between RNA and DNA

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

What are polysaccharides?

Polysaccharides are complex carbohydrates formed by long chains of monosaccharides, like starch and glycogen.

Question: What is the function of enzymes?

Enzymes speed up biochemical reactions by lowering the activation energy.

List two examples of lipids.

- Phospholipids - Steroids
