What is the primary purpose of the light reactions of photosynthesis? a. to product glucose b. to release electrons needed to convert solar energy to chemical energy such as ATP c. to create oxygen gas d. to remove carbon dioxide gas from the atmosphere ...
During the process of cellular respiration, which is the final acceptor for electrons at the end of the electron chain? A. Oxygen B. Carbon C. Carbon dioxide D. Hydrogen E. Water The Oxygen released during Photosynthesis comes from the breakdown of which of the follo...

During oxygenic photosynthesis, light energy transfers electrons from water (H2O) taken up by plant roots to CO2 to producecarbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water is "oxidized," or loses electrons. Oxygen is produced along with carbohydrates. ...
It is colorless and odorless gas at room temperature. When the temperature drops below -78 °C at normal pressure, it becomes solid (this is called dry ice). CO2 is one of the most important gases on earth and is used in a process called photosynthesis. Photosynthesis takes place in ...
Photosynthesis produced a waste product, oxygen, which was poisonous to the first organisms on Earth. This oxygen, released in great quantities into the atmosphere wreaked havoc on other primitive organisms, leaving the field clear for the cyanobacteria.光合作用产生了一种“废物”——氧气，它对地球上...
During photosynthesis, plants absorb carbon dioxide from the atmosphere and turn it into glucose and oxygen. The process requires energy in the form of sunlight and is more endogenic than it is endothermic. The equation for the reaction is: ...
Similarly, theWorld Resources Institute(WRI) says net zero “will be achieved when all emissions released by human activities are counterbalanced by removing carbon from the atmosphere in a process known as carbon removal.” Simply put, it is a state where emissions are balanced with an equal amo...
They are also developing methods that convert solar energy and water directly to hydrogen by harnessing and mimicking biological processes likephotosynthesis. There are several ways to use hydrogen for energy once it is produced. The most prominent is in fuel cells, which convert the chemical energy...
Modern global warming is caused by humans. The burning of fossil fuels has releasedgreenhouse gasesinto the atmosphere, which trap warmth from the sun and drive up surface and air temperatures. Global warming is a synonym for climate change, though "climate change" has become the preferred term...
