High oxygen levels inhibit photosynthesis because oxygen competes with carbon dioxide for the active site on the enzyme RuBisCO, which is essential for the first step of photosynthesis. This competition reduces the efficiency of carbon dioxide fixation and ultimately hinders the overall process of photosynthesis.
What else can I help you with?
What is responsible for high levels of oxygen in Earth's atmosphere a. Photoautotrophs b. photoheterotrophs c.chemoautotrophs d. chemoheterotrophs that perform decomposition e.parasitic chemoheter..?
a. Photoautotrophs. These are organisms like plants, algae, and cyanobacteria that use sunlight to convert carbon dioxide into oxygen through photosynthesis, which ultimately leads to the high levels of oxygen in Earth's atmosphere.
Which factors affect the rate of photosynthesis and how?
Factors that affect the rate of photosynthesis include light intensity, carbon dioxide levels, and temperature. Higher light intensity usually leads to faster photosynthesis, as does higher carbon dioxide levels. However, extremely high temperatures can inhibit the process as they can damage the enzymes involved.
Why was there more oxygen in the air millions of years ago?
Millions of years ago, there was more oxygen in the atmosphere due to high levels of photosynthesis by ancient plants. These plants absorbed carbon dioxide and released oxygen as a byproduct, leading to higher oxygen concentrations in the air.
What two things will be produced by plants from photosynthesis?
Plants produce oxygen and glucose through the process of photosynthesis. Oxygen is released into the atmosphere as a byproduct, while glucose is used as an energy source for the plant's growth and development.
In excess of oxygen the enzyme Rubisco participates in?
In excess of oxygen, the enzyme Rubisco participates in a process called photorespiration. This process occurs when oxygen outcompetes carbon dioxide as a substrate for Rubisco, leading to a series of reactions that reduce the efficiency of photosynthesis. Photorespiration happens in plants to mitigate the effects of high oxygen levels, particularly under conditions like high temperatures or drought stress.
What happens to the rate of oxygen production when more than 200ppm CO2 is added?
When more than 200ppm of CO2 is added, the rate of oxygen production during photosynthesis may decrease. This is because high levels of CO2 can inhibit the enzymes responsible for photosynthesis in plants, leading to a decrease in oxygen production.
Which of the gases below is found at high levels near the surface of the ocean due to plant photosynthesis?
Oxygen is found at high levels near the surface of the ocean due to plant photosynthesis. Plants in the ocean, like phytoplankton, produce oxygen as a byproduct of photosynthesis, leading to high concentrations of oxygen in the surface waters.
What gas is found in high levels near the the surface of the ocean due to plant photosynthesis?
Oxygen is the gas that is found in high levels near the surface of the ocean due to plant photosynthesis. Plants use sunlight to convert carbon dioxide into oxygen as a byproduct, which enriches the water with oxygen.
How does carbon oxcide level affect oxygen production?
Carbon dioxide levels affect oxygen production indirectly by influencing the rate of photosynthesis in plants. Higher carbon dioxide levels can stimulate photosynthesis, leading to increased oxygen production as a byproduct. However, if carbon dioxide levels get too high, it can also disrupt the balance of ecosystems, potentially affecting oxygen production in the long term.
Which of the following is true of phosphofructokinase (PFK)?
High levels of ATP inhibit PFK
Is photosynthesis the reason the atmosphere is rich in oxygen gas?
Yes, photosynthesis is the primary process responsible for producing oxygen in the atmosphere. During photosynthesis, plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is released into the atmosphere as a byproduct, contributing to the high levels of oxygen present today.

a. Photoautotrophs. These are organisms like plants, algae, and cyanobacteria that use sunlight to convert carbon dioxide into oxygen through photosynthesis, which ultimately leads to the high levels of oxygen in Earth's atmosphere.
Where does the oxygen cycle move fastest?
The oxygen cycle moves fastest in marine ecosystems, especially in areas with high levels of biological activity such as coral reefs and coastal regions. Here, the constant exchange of oxygen through photosynthesis and respiration by marine organisms helps maintain oxygen levels and support diverse ecosystems.
What gas is found in high levels near the surface of the ocean due to plant photosynthesis?
The primary gaseous byproduct of photosynthesis is oxygen (O2) so it would be in higher levels than the atmosphere further away from the surface. Even near the ocean surface, however, the gas in highest concentration is still nitrogen (N2) which makes up about 79% of the gas in the earth's atmosphere. Near the ocean surface it would probably dip to a much lower level due to the oxygen being given off by photosynthesis, but would probably still be well over 50% .
Do coral reefs grow well in high levels of oxygen?
yes, coral reefs do grow well in high levels of oxygen.
Which factors affect the rate of photosynthesis and how?
Factors that affect the rate of photosynthesis include light intensity, carbon dioxide levels, and temperature. Higher light intensity usually leads to faster photosynthesis, as does higher carbon dioxide levels. However, extremely high temperatures can inhibit the process as they can damage the enzymes involved.
