MDCAT Quick Notes By MDCAT

The MDCAT exam, which stands for Medical and Dental Colleges Admission Test, was first introduced in the year 1998 to aid students in passing medical examinations to pursue medical and dental courses in Pakistan. Like many other tests, the PMC MDCAT exam has its own set of biology, chemistry, and physics important points that should be studied before appearing in the examination hall. Here’s an overview of these three subjects that you need to know before appearing in the exam

Molecular Structure

To understand how cells work, you need to understand molecular structure. Atoms are the basic units of matter and are made up of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electrons orbit the nucleus of an atom in shells. The types of elements are determined by the number of protons in the nucleus.

Atoms and Elements

All matter is made of atoms, which are the smallest units of an element. Elements are made up of different types of atoms that have different properties. The three main states of matter are solid, liquid, and gas. The physical and chemical properties of atoms determine how they interact with other atoms to form compounds.

Classification of Living Things

All living organisms can be classified into one of six major groups: plants, animals, fungi, protists, archaea, or bacteria. The criteria used to classify living things include cell type, nutrition type, body plan, and reproduction method.

The Cell Structure

The cell is the basic unit of life. All living things are made up of cells. Cells are tiny, usually only a few micrometres in diameter. The three main parts of a cell are the nucleus, cytoplasm, and cell membrane. The nucleus contains the cell’s DNA, which controls the cell’s activities. The cytoplasm is where most of the chemical reactions in the cell take place.

Enzymes & Their Role in Metabolism

Enzymes are proteins that catalyze chemical reactions in the body. Enzymes can be found in all body tissues, including the liver, pancreas, and muscles. Enzymes are important for metabolism, as they help to break down food into nutrients that can be used by the body.

Mendel’s Law of Inheritance

Gregor Mendel was an Austrian monk who is often called the father of genetics. He conducted experiments with pea plants and discovered that certain laws govern how traits are inherited. Mendel’s laws are important when studying biology, chemistry, and physics.

Nucleic Acids – DNA & RNA and their structure

Nucleic acids are important macromolecules that make up our DNA and RNA. DNA is responsible for encoding our genetic information, while RNA is responsible for carrying out the instructions of DNA. The structure of nucleic acids is essential to their function. DNA consists of two strands of nucleotides coiled around each other to form a double helix. RNA is a single strand of nucleotides.

Different types of cells in a multicellular organism

There are many different types of cells in a multicellular organism. Each type of cell has a specific function. The four main types of cells are epithelial cells, muscle cells, nerve cells, and connective tissue cells.

The Brain Structure & Functions

The brain is the control centre of the body. It sends and receives signals to and from all parts of the body. The brain is made up of many different parts that work together. The cerebrum is the largest part of the brain. It controls voluntary actions like walking and talking. The cerebellum controls balance and coordination. The medulla oblongata controls involuntary actions like breathing and heart rate.

Different kinds of tissues in an animal body

There are four different types of tissues in the animal body- epithelial, connective, muscle, and nervous. Each type of tissue has a specific function. Epithelial tissue covers the body and helps protect it from infection. Connective tissue binds together different parts of the body. Muscle tissue helps the body move. Nervous tissue transmits signals from the brain to the rest of the body.
