What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
What must photosynthetic bacteria provide before any eukaryotes could evovlve?
Oxygen. Photosynthetic bacteria were essential in producing oxygen through photosynthesis, which created an oxygen-rich atmosphere. This new oxygenated environment allowed for the evolution of aerobic metabolism in eukaryotes.
What it call when the mitochondria in cells today are the descendants of aerobic prokaryotes that used oxygen to generate energy?
This phenomenon is known as endosymbiosis, specifically referring to the theory that mitochondria and chloroplasts originated from free-living aerobic prokaryotes that were engulfed by ancestral eukaryotic cells and established a symbiotic relationship.
Is streptococcus aerobic or anaerobic?
Streptococcus is a facultative anaerobe, meaning it can grow in both aerobic (with oxygen) and anaerobic (without oxygen) conditions.
Is the organelle where aerobic respiration takes place?
The organelle where aerobic respiration takes place is the mitochondrion. It is often referred to as the "powerhouse" of the cell because it produces the majority of the cell's ATP, which is the main energy currency of the cell. Mitochondria have their own DNA and are believed to have originated from a symbiotic relationship between ancestral eukaryotic cells and bacteria.
What are some examples of a photosynthetic?
Chromatium (anaerobic). Cyanobacterial (aerobic).
What caused an aerobic atmosphere during the history of the earth?
The origin of photosynthetic prokaryotes caused an aerobic atmosphere during the history of the earth.
What step caused an aerobic atmosphere during the history of earth?
The evolution of photosynthetic organisms, such as cyanobacteria, led to the buildup of oxygen in Earth's atmosphere through a process called the Great Oxidation Event. This occurred around 2.4 billion years ago, gradually transforming the atmosphere from anaerobic to aerobic.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
What is the origin of chloroplasts?
Chloroplasts originated from a process called endosymbiosis, where a eukaryotic cell engulfed a photosynthetic cyanobacteria. Over time, a symbiotic relationship developed where the cyanobacteria became integrated into the cell and evolved into what we now recognize as chloroplasts. This event is believed to have occurred around 1.5 billion years ago, contributing to the evolution of photosynthetic organisms.
How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
What must photosynthetic bacteria provide before any eukaryotes could evovlve?
Oxygen. Photosynthetic bacteria were essential in producing oxygen through photosynthesis, which created an oxygen-rich atmosphere. This new oxygenated environment allowed for the evolution of aerobic metabolism in eukaryotes.
Which gas given off by autotrophic activity made the evolution of aerobes possible?
Oxygen, produced during the process of photosynthesis by autotrophs, was a gas that made it possible for aerobic respiration to evolve. This process allowed for more efficient energy production in organisms, leading to the development and success of aerobic organisms.
What are 3 feeding strategy groups of protists?
The different strategies are mixotrophs, autotrophs, heterotrophs, and some are aerobic and have a mitochondria.
What poison makes a large amount of aerobic respiration?
Cyanide is a potent poison that inhibits aerobic respiration. It works by binding to cytochrome c oxidase in the electron transport chain, preventing the utilization of oxygen for ATP production. As a result, cells are unable to complete aerobic respiration, leading to a buildup of anaerobic metabolic byproducts and eventual cellular death.
Why did the mitochondria originate?
Mitochondria likely originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria. This symbiosis allowed for more efficient energy production through aerobic respiration, providing a survival advantage which led to the integration of the bacteria as mitochondria within eukaryotic cells.
What is the relationship between aerobic respiration and exercise?
aerobic refers to the utilization of oxygen. exercise that raises the heart rate to a target level for a set time will condition the heart and lungs making them more oxygen efficient.
