What part of a car is like the cytoskeleton?
The cytoskeleton does the same job as a frame of a car. The frame holds the rest of the car in place, where the cytoskeleton holds the rest of the cell in place. It holds most of the cell structures inside of its frame like structure.
How a cell is like a school?
The Cell Wall is like the beams in a school because it provides the school support. The Chloroplast is like the cafeteria in a school because it is where the students in a school get their energy. The Large Central Vacuole is like a swimming pool because it stores water for the swim team.
What part of a car is like a cell membrane?
A CELL IS LIKE A CAR. The plasma membrane is the outer layer, so you could say that the physical outer body of the car is like the plasma membrane. Nucleus. Just as the car base holds the car together so the cytoplasm holds parts together.
What part of a car is like a Centriole?
chloroplast
What would a ribosome be in a car?
Ribosomes are like gasoline in the car. Ribosomes produce proteins like gasoline produces energy to make the car move.
What does the Golgi body do?
The Golgi apparatus transports and modifies proteins in eukaryotic cells. How have scientists studied dynamic protein movements through the Golgi? The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.
What’s a mitochondria do?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What are the three functions of mitochondria?
1. to perform cellular respiration . 2.to form A.T.P. 3.to oxidise the food to provide energy to the cell ..
What is mitochondria in simple words?
Mitochondria (sing. mitochondrion) are organelles, or parts of a eukaryote cell. They are in the cytoplasm, not the nucleus. They make most of the cell’s supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. This means mitochondria are known as “the powerhouse of the cell”.
Why do liver cells have lots of mitochondria?
For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.
What organ has the most mitochondria?
heart muscle cells
What simple sugar is broken down in the mitochondria?
Glucose
Do liver cells have more mitochondria than muscle cells?
Answer. since liver cells are highly regenerative and muscle cells need high energy for contraction and expansion these cells require high energy… so the energy generating organelle mitochondria is more on liver and muscle cells.
Why do skin cells have less mitochondria than muscle cells?
Cellular respiration occurs in mitochondria. Therefore, cells that are more active usually contain more mitochondria than cells that are not as active. Since muscle cells are required for the movement of an organism, they will have more mitochondria than skin cells.
Why does a cell need energy?
All living cells need energy to function in order for the chemical reactions occurring in the cells to take place. In humans this energy is obtained by breaking down organic molecules such as carbohydrates, fats and proteins.
Why do liver cells have lots of ribosomes?
Liver cells contain more ribosomes than fat cells because the liver is an organ in which much protein synthesis occurs, and ribosomes are the cell…
What cells have lots of rough ER?
Cells that specialize in protein secretion contain large amounts of rough endoplasmic reticulum. For instance, cells of the pancreas that produce the protein insulin, have abundant rough endoplasmic reticulum.
Do liver cells have vesicles?
Although there are different kinds of vesicles, each with their own secretion and capture biology, all of them carry a cargo of proteins, lipids, metabolites and nucleic acids. Different liver cell types, including hepatocytes, cholangiocytes and stellate cells, secrete and capture EVs and interact with them.
What cells have more ribosomes?
Because protein synthesis is an essential function of all cells, ribosomes are found in practically every cell type of multicellular organisms, as well as in prokaryotes such as bacteria. However, eukaryotic cells that specialize in producing proteins have particularly large numbers of ribosomes.
How many ribosomes are in a cell?
10 million ribosomes
What makes ribosomes in a cell?
A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits….What makes ribosomes in a cell?
| A | B |
|---|---|
| Nucleolus | A small, dense region in the nucleus that makes ribosomes |
| Nucleus | Controls most cell processes and contain the hereditary information of DNA |
Why do muscle cells have lots of ribosomes?
Amino acids are the building blocks of proteins. Ribosomes are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes.
Do muscle cells have cilia?
Now, scientists have shown that cellular antennae called cilia, found on fat-forming cells interspersed in muscle, play a key role in this muscle-to-fat transformation. Like it or not, as we age, our muscle cells are slowly exchanged, one by one, for fat cells.
What cell organelle is like the muscular system?
mitochondria
What extra organelles do muscle cells have?
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.
