What makes muscle cells unique?
Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
Why do red blood cells and muscle cells have different structures?
During differentiation different parts of the DNA in each type of cell are activated resulting in the different structure and function of the cells.
Why are muscle cells different than nerve cells?
The main difference between muscle cells and nerve cells is that muscle cells are responsible for the contraction and relaxation of muscles whereas nerve cells are responsible for the coordination of the functions of the body through the transmission of nerve impulses between the body and the central nervous system.
Why are muscle cells different from skin cells?
Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. See the images below for more info on skin and muscle cells' shape and general appearance.
How are muscle cells adapted to their function?
All muscle cells have layers of protein filaments in them. These layers can slide over each other causing muscle contraction. Muscle cells have a high density of mitochondria to provide sufficient energy (via respiration) for muscle contraction.
What organelles are unique to muscle cells?
To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell's “power plants,” convert nutrients into the molecule ATP, which stores energy.
What do muscle cells have that other cell types do not?
They have multiple nuclei within each cell. This contrasts with the majority of other cells in human bodies. They also contain many mitochondria, cellular organelles that produce adenosine triphosphate (ATP), the body's fuel.
What is the difference between a muscle cell and a nerve cell use the words tissue specific differentiation gene expression and proteins in your answer?
Use the words Tissue Specific, Differentiation, Gene Expression, and Proteins in your answer. Muscle cells and nerve cells have distinct gene expression patterns. In a muscle cell, tissue-specific genes are turned on (for example, actin and myosin), whereas gene expression in a nerve cell is different.
How are nerve cells different from blood cells?
Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
Why are nerve cells different from muscle cells quizlet?
Explanation. Muscle and nerve cells differ in how they were constructed. This difference is that they use different genetic codes. Genetic codes are responsible for the coding of proteins to be synthesized.
What makes each cell different?
The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
Why do different cells have different functions?
The structural and functional characteristics of different types of cells are determined by the nature of the proteins present. Cells of various types have different functions because cell structure and function are closely related.
What is the purpose of a muscle cell?
Muscle cells are specialized to contract, i.e. create a pulling force to stabilize or move parts of the body. There are three types of muscle cell: skeletal, visceral and cardiac.
Why are muscle cells long and stretchy?
The muscle cell is long so it can contract and relax with other cells.
How is a muscle cell adapted to its function?
All muscle cells have layers of protein filaments in them. These layers can slide over each other causing muscle contraction. Muscle cells have a high density of mitochondria to provide sufficient energy (via respiration) for muscle contraction.
What structural and functional properties of muscle cells are different from other body cells?
Different Muscle Lengths They have multiple nuclei within each cell. This contrasts with the majority of other cells in human bodies. They also contain many mitochondria, cellular organelles that produce adenosine triphosphate (ATP), the body's fuel.
Why do muscle and nerve cells have different proteins but the same DNA?
In fact, there is a common set of genes to which they can both bind, but differences between their DNA-binding regions allow each of the two proteins to also turn on their own unique sets of genes, which is what enables one to make muscle cells while the other makes neurons.
Why do you think muscle and nerve cells are long where as blood cells are circular?
Muscle cells are long in order to provide maximum strength and also because they are involved in conduction. same is seen in the case of nerve cells or more generally neurons. Blood cells are shaped in such a way in order to provide maximum surface area to volume ratio.
How can nerve cells and muscle cells differ in structure and function but come from the same original cell quizlet?
How can nerve cells and muscle cells differ in structure and function but come from the same original cell? Each cell expresses a different subset of genes. Each cell has different genes.
Do nerve cells and muscle cells contain different DNA?
We learned in biology class that every cell in the body has the same DNA. Whether a heart cell, skin cell or muscle cell—they all read from the same genetic blueprint.
Why do cells have different organelles with different functions?
Together, the total area of a cell's internal membranes far exceeds that of its plasma membrane. Like the plasma membrane, organelle membranes function to keep the inside "in" and the outside "out." This partitioning permits different kinds of biochemical reactions to take place in different organelles.
How is it that cells of the body are able to differentiate?
In order for a cell to differentiate into its specialized form and function, it need only manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.
How can two cells in the same individual have very different structures and functions?
Gene regulation makes cells different These different patterns of gene expression cause your various cell types to have different sets of proteins, making each cell type uniquely specialized to do its job.
How is the muscle cell adapted to its function?
Adaptations of Muscle Cells Muscle cells have many mitochondria to provide energy for movement. Muscle cells have muscle fibres which can relax and contract to change the shape of the cell.
How is a muscle cell adapted for its function?
Adaptations of Muscle Cells Muscle cells have many mitochondria to provide energy for movement. Muscle cells have muscle fibres which can relax and contract to change the shape of the cell.
Why do muscle cells have lots of mitochondria?
Muscles require a large amount of energy to function. This is provided primarily by mitochondria in cells that consume a lot of energy. We therefore find more of these powerhouses of the cell in muscle cells than in other cell types with a lower metabolic rate.
Why are muscle cells long?
The muscle cell is long so it can contract and relax with other cells.
How is it that bone cells and muscle cells differ in structure and function?
muscle cells have contractile proteins and bone cells do not. bone cells secrete bone matrix and muscle cells do not.
Which type of cell has many mitochondria?
heart muscle cells A. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!
Which best explains why muscle cells are different from blood cells Quizizz?
Which best explains why muscle cells are different from blood cells? A mutation occurs during the development of muscle cells but not in blood cells.
