The cell wall gives the cell structure and so do the beams of the stadium. 3. Mitochondria - The mitochondria in a cell is like the crowd at a baseball game. The mitochondria gives the cell energy just like the crowd does at a baseball game. The crowd gets the players pumped up by cheering and yelling.
Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell.
Neurons come in all shapes and sizes, however most have three imperative parts: a cell body that contains the core and coordinates the exercises of the neuron; dendrites, short filaments that get messages from different neurons and hand-off them to the cell body; and an axon, a long single fiber that conveys messages from the cell body to dendrites of different neurons. Symptoms:
The nucleus contains the DNA, with genetic codes that helps to shape the inherited traits. The cytoplasm is like a workshop in the cell, where most functions occur. Mitochondria in the cell which provides energy from the conversion of food, which let the human body to function. They are tiny compartments found within cells and they perform lots of
This essay will be discussing the differences in the two cells with reference to the metabolic processes and storage of genetic information. The most obvious difference is the nucleus and the lack there of a nucleus. In prokaryotes, there is one long chromosome or circular DNA called the nucleoid. This results in the DNA being much simpler than
Atoms link together in different patterns to build molecules that perform important functions of life. Molecules are combined to build cellular organelles which are called the inner organ of a cell. 2. Cellular level – which is the smallest unit of living matter (combined of cells). Every type of cells transmits various tasks inside the human body regardless of their common functions, each
rRNA forms a part of both subunits on a ribosome, in which proteins are assembled. tRNA take amino acids to the ribosome and matches them to the coded mRNA message. 1c. Infer: Why is it important for a single gene to be able to produce hundreds or thousands of
The eukaryotic cell’s most important component is the nucleus. This is a compartment that is surrounded by membranes that houses the DNA that is eventually divided into chromosomes. The nucleus protects the eukaryotic cell from damage that could occur on a day-to-day basis.
The nucleus is generally in the center of a cell. A typical cell nucleus is so small that ten thousand could fit on the tip of a needle. One strand of DNA is around 6 feet long. This mean that 6 feet of DNA fits inside the nucleus, which occupies about 10% of a total cell (https://en.wikipedia.org/wiki/Cell_nucleus), of a microscopic cell. For this to happen eight separate histone protein subunits attach to the DNA molecule to
P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue.
The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.
