Where does the oxygen that we breathe come from? (Multiple Choice)

Biology
1 answer:
satela [25.4K]3 years ago
6 0

Answer:

Water

Explanation:

Scientists agree that there's oxygen from ocean plants in every breath we take. Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water's surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food.

Hope this helped, Have a Wonderful Day!!

Although glycolysis produces four molecules of atp by substrate-level phosphorylation, the net gain of atp for the cell is two m
omeli [17]

Although glycolysis produces four molecules of atp by substrate-level phosphorylation, the net gain of atp for the cell is two molecules. This is because glycolysis is at first endergonic.

<h3>What is glycolysis?</h3>
  • The metabolic process that turns glucose into pyruvic acid is known as glycolysis.
  • The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process.
  • A series of ten enzyme-catalyzed processes make up glycolysis.
  • The process by which glucose is broken down to provide energy is known as glycolysis.
  • It generates two pyruvate molecules, ATP, NADH, and water.
  • There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
  • Both aerobic and anaerobic creatures experience it.
  • The initial process in breaking down glucose to release energy for cellular metabolism is called glycolysis.
  • An energy-consuming phase and an energy-releasing phase make up glycolysis.

Which respiratory-associated muscles would contract or relax during forced expiration, for example blowing up a balloon?
Nutka1998 [239]
The correct answer is B, internal intercostal muscles and abdominal muscles would contract.
Exhalation is the flow of the breath out of the body. During forced exhalation, internal intercostal muscles contracts which lower the rib cage and decrease thoracic volume, while the abdominal muscles push up on the diaphragm which causes the thoracic cavity to contract.
