What are the similarities between mitochondria and chloroplasts?
Like mitochondria, chloroplasts produce food for their cells.
Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis.
Like the mitochondria, the chloroplast has an inner and outer membrane..
What are the similarities between mitochondria and bacteria?
Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria’s genome, but much smaller.
Can chloroplasts and mitochondria reproduce themselves?
Replication. Mitochondria and chloroplasts make more of themselves in much the same way as bacteria reproduce. … Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.
What is the main function of ribosome?
Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).
What gas is an end product derived from the breakdown of sugar?
This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. Sugars are particularly important fuel molecules, and they are oxidized in small steps to carbon dioxide (CO2) and water (Figure 2-69).
What part of respiration produces the most ATP?
Electron transport chainElectron transport chain The electron transport chain is the last stage of the respiration pathway and is the stage that produces the most ATP molecules. Electron transport begins with several molecules of NADH and FADH 2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.
What do the nucleus chloroplasts and mitochondria have in common?
Chloroplasts. Similar to the nucleus, chloroplasts and mitochondria are membrane-bound and stocked with a strategic set of enzymes. … Both plant and animal cells have mitochondria because both participate in aerobic respiration.
What bacteria did mitochondria come from?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
What are two common characteristics of mitochondria and chloroplasts?
Describe at least two common characteristics of chloroplasts and mitochondria. Both organelles are involved in energy transformation, mitochondria in cellular respiration and chloroplasts in photosynthesis. They are both composed of two or more separate membranes.
What are the two similarities between mitochondria and plastids?
Both mitochondria and plasmids are double membrane bound organelles. Both mitochondria and plastid in their outer membrane have porin protein which makes outer layer more permeable. Both mitochondria and plasmids have some of their own DNA for protein synthesis hence they are called as semi autonomous cell organelles.
What do mitochondria and thylakoid membranes have in common?
Answer and Explanation: The mitochondrial membrane and thylakoids membranes have a couple things in common: Both membranes contain ATP Synthase Proteins.
Why do chloroplasts and mitochondria have double membranes?
The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The inner membrane, which now contains numerous folds, apparently came from the bacterial membrane, while the outer membrane came from the host cell itself.
Why does the mitochondria have two membranes?
They are the reason that we need oxygen at all. The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller, unwrinkled bag. The two membranes create distinct compartments within the organelle, and are themselves very different in structure and in function.
Do bacteria have ER?
many membrane bound organelles- lysosomes, mitochondria (with small ribosomes), golgi bodies, endoplasmic reticulum, nucleus. Large ribosomes in cytoplasm and on rough ER. … Bacteria, of course, have no nucleus and therefore also nuclear membrane.
How do the mitochondria and chloroplasts work together?
How do the chloroplast and mitochondria work together to keep plant cells alive? Chloroplasts convert sunlight into food during photosynthesis, then mitochondria makes energy out of the food in the form of ATP. where critical chemical reactions occur in the cell that allow for the release of energy from food.
What can mitochondria be compared to?
Function: acts like a digestive system which takes in nutrients, breaks them down, and creates energy for the cell. Analogy: Mitochondria can be compared to sports programs because sports programs give energy to athletes just as the mitochondria gives energy to the cell.
Where is most of ATP produced?
mitochondriaThe Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.
What three things do mitochondria and prokaryotic bacteria have in common?
Even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.
