What is abundant in skeletal muscle?
Potassium is the most abundant mineral in muscles. It works closely with sodium in muscle function. All other minerals are present only in traces. So, the correct option is 'potassium'.

Answer: Chloroplast is abundant in palisade cell.
Which of the following is seen most abundant in bones?
Calcium is the most abundant mineral in the human body, making up 1.5 to 2% of the total body weight. Approximately 1,200 g of calcium are present in the body of an adult human; more than 99% of that amount is found in bones.
What are the components of skeletal muscle?
Skeletal muscles contain connective tissue, blood vessels, and nerves. There are three layers of connective tissue: epimysium, perimysium, and endomysium. Skeletal muscle fibers are organized into groups called fascicles.
What is Golgi apparatus function?
The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
What organelle is more abundant in the palisade mesophyll cells?
Structures. Palisade cells contain the largest number of chloroplasts per cell, which makes them the primary site of photosynthesis in the leaves of those plants that contain them, converting the energy in light to the chemical energy of carbohydrates.
What is the most abundant element in the body?
Oxygen Oxygen is the most common element in the human body, comprising approximately 65.0% of body mass. Most of the oxygen present is found in the form of water.

What are muscle cells made of?
As seen in the image below, a muscle cell is a compact bundle of many myofibrils. Each myofibril is made of many sarcomeres bundled together and attached end-to-end. A specialized form of the endoplasmic reticulum, known as the sarcoplasmic reticulum, extends in and around these myofibril bundles.
What structure in skeletal muscle cells function in calcium storage?
sarcoplasmic reticulum, intracellular system of closed saclike membranes involved in the storage of intracellular calcium in striated (skeletal) muscle cells.
What is the function of mitochondria and Golgi bodies?
Mitochondria : It performs the function of respiration and provides the cell with energy. It is called the power house of cell. Golgi bodies : These collect and distribute substances made in cell, synthesis and secretions of many materials. Ribosomes : They help in the synthesis of proteins.
Why is the Golgi apparatus the most important organelle?
The Golgi Apparatus is important because it processes and packages protein and lipid. without the golgi apparatus you would lose your DNA, because DNA is composed of protein.
What organelles are found in skeletal muscle cells?
During strenuous exercise, the rate of energy use in skeletal muscles can increase by more than 100-fold almost instantly. 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.
Which organelle is found in abundance in cells with a high rate of respiration?
Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria.
Which one is the second most abundant element in human body?
Carbon Carbon is the second most abundant element in the human body, accounting for 18% of body weight.
Which is the most abundant minerals in the body?
Calcium is the most plentiful mineral found in the human body. The teeth and bones contain the most calcium. Nerve cells, body tissues, blood, and other body fluids contain the rest of the calcium.
What is the most abundant substance in the body?
By mass, oxygen is the most abundant element in the human body.
What organelles are in skeletal muscle cells?
During strenuous exercise, the rate of energy use in skeletal muscles can increase by more than 100-fold almost instantly. 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.
Do muscle cells have the most mitochondria?
It takes place in the mitochondria and consumes oxygen. Due to their relatively high energy demand, muscle cells require a particularly high number of mitochondria compared to other cell types.
What do skeletal muscle cells have more of?
Skeletal muscle cells have high energy requirements, so they contain many mitochondria in order to generate sufficient ATP. Skeletal muscle cells, a striated muscle cell type, form the muscle that we use to move, and are compartmentalized into different muscle tissues around the body, such as that of the biceps.
What is the role of Ribosomes and Golgi body?
Proteins generated by the ER's ribosomes are packed in the Golgi apparatus, where lipids wrap them in a membrane that is then exported from cells. Molecules that enter the Golgi are charged, stored, and then released into the cytoplasm (secretory vesicles).
What is the most important organelle in cells?
Of all eukaryotic organelles, the nucleus is perhaps the most critical. In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and the process of interpreting it begins.
What are lysosomes responsible for?
Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.
What are skeletal muscles composed of?
muscle fibers Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium.
What cells are abundant in mitochondria?
Of all the cells in human body, its the heart muscle cells with about 5,000 mitochondria per cell that contain far more mitochondria than any other organ in human body.
What type of cell has abundant ribosomes?
Ribosomes are remarkably abundant in cells. A single actively replicating eukaryotic cell, for example, may contain as many as 10 million ribosomes. In the bacterium Escherichia coli (a prokaryote), ribosomes may number as many as 15,000, constituting as much as one-quarter of the cell's total mass.
Which is most abundant in human body?
Oxygen Oxygen is the most abundant element in the human body.
What is the most abundant substance in living cells?
Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
Do muscle cells have a lot of ribosomes?
Why do muscle cells have lots of ribosomes? Because proteins synthesis is an essential function of all cells ribosomes are found in practically every cell. Ribosomes are particularly abundant in cells that synthesize large amounts of protein.
What organelles are the most numerous inside cells?
- Ribosomes are known as protein factories because they are the main site of protein synthesis.
- They are composed of ribonucleic acids and proteins.
- It is the smallest and most abundantly found cellular organelle.
