What are the molecules that make up a cell?
Where is ATP synthesized in eukaryotic cells?
How many membrane layers does the mitochondrion have?
Which is one of the main energy transformers of cells in a process called cellular respiration?
Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration.
What is known as the ups of the cell?
The ubiquitin-proteasome system (UPS) is the major proteolytic system in the cytosol and nucleus of all eukaryotic cells (reviewed in Weissman et al.
What is the mitochondria in biology?
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).
How energy is generated in mitochondria?
At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane, through ATP synthase.
What are the 3 main parts of a cell and their functions?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Which organelle is known as the transport channel of the cell?
Endoplasmic reticulumTransporting channels of the cell is Endoplasmic reticulum.
What is the other name of mitochondria?
the powerhouse of the cellHence, mitochondria are also known as the powerhouse of the cell. Mitochondria are present only in eukaryotic cells. Mitochondria are also known as chondriosome or sarcosome.
Why mitochondria is called the powerhouse of cell?
The proteins synthesized by the proteins in mitochondria are utilized to generate adenosine triphosphate (ATP) from the food. This ATP acts as the energy currency of the cell, because of which the whole cell and body get energy. Thus, mitochondria are called the powerhouse of the cells.
Which part of mitochondria produces ATP?
The inner membrane of the mitochondrion contains the components of the electron transport chain. Oxidation/reduction reactions along the components of the electron transport chain generate a proton gradient that is used by ATP synthase to phosphorylate ADP, thereby producing ATP.
Who produces cell energy?
Mitochondria is responsible for the production of energy in the cell.
What form of energy is ATP?
chemical energyAnswer and Explanation: The form of energy that is in ATP is called chemical energy. Chemical energy is a type of potential energy and is stored energy within chemical bonds. ATP, adenosine triphosphate, is a molecule with an adenine nucleotide attached to three phosphate groups.
Where is ATP produced?
mitochondrial matrixThe majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.
How is the Golgi apparatus like a UPS?
The Golgi Apparatus is like a UPS truck because the golgi apparatus packages and ships proteins where they are needed like a UPS truck packages and ships items where they are needed. 8. Vacuoles- Store water, nutrients and even wastes.
Where in the cell is DNA located?
cell nucleusMost DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
Is a ribosome an example of a cell?
“Ribosomes are one of the most important cell organelles composed of RNA and protein that converts genetic code into chains of amino acids.”
What type of proteins would be used in cell to cell recognition?
Glycoproteins are one type of membrane protein that can carry out cell recognition.
What are the molecules that make up a cell?
39. A cell has the following molecules and structures: enzymes, DNA, ribosomes, plasma membrane, and mitochondria. It could be a cell from
Where is ATP synthesized in eukaryotic cells?
In eukaryotic cells, ATP is synthesized primarily on the inner membrane of the mitochondria. Where are the corresponding reactions likely to occur in prokaryotic respiration?
How many membrane layers does the mitochondrion have?
40. The mitochondrion, like the nucleus, has two or more membrane layers. How is the innermost of these layers different from that of the nucleus?
What are the molecules that make up a cell?
a cell has the following molecules and structure enzymes,DNA,ribosomes, plasma membrane and mitochondria. it could be a cell from..
Which cells will incorporate radioactively labeled amino acids into proteins?
cells of the pancreas will incorporate radioactively labeled amino acids into proteins.this tagging of newly synthesized proteins enable a researcher to track their location. in this case we are tracking an enzyme secreted by pancreatic cells. what is most likely pathway?
What causes the cilia and flagella to move relative to each other?
movement of cilia and flagella is the result of motor proteins causing microtubles to move relative to each others
Does cyanide make ATP?
cyanide binds with at least one molecule involving in producing ATP. If a cell is exposed to cyanide most of the cyanide would be found within the..
