What produces O2 as a waste product?

What produces O2 as a waste product?

Oxygen is given off during photosynthesis as a waste product. This is the reaction that only plants and some algae and bacteria can do. They take sunlight and combine carbon dioxide (CO2) and water (H2O). They create glucose (C6H12O6) and oxygen gas (O2).

What is the process that releases oxygen?


What is the ultimate source of all the food we eat and the oxygen we breathe?


Question Answer
The ultimate source of all the food we eat and the oxygen we breathe is photosynthesis
Plants use sugars as a fuel for cellular respiration and a starting material for making other organic molecules
Plant cells have mitochondria and chloroplasts

What is the ultimate source of oxygen?

Oxygen Supply Phytoplankton absorb both across their cell walls. In the process of photosynthesis, phytoplankton release oxygen into the water. Half of the world’s oxygen is produced via phytoplankton photosynthesis. The other half is produced via photosynthesis on land by trees, shrubs, grasses, and other plants.

What is the name given to organisms that can make?

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers….Vocabulary.

Term Part of Speech Definition
soil noun top layer of the Earth’s surface where plants can grow.

What yields energy the quickest?


What is the oxidation of glucose to pyruvic acid called?


What type of metabolic pathway requires oxygen?

Aerobic Glycolysis

What happens to pyruvic acid if there is no oxygen?

Pyruvic acid supplies energy to living cells through the citric acid cycle (also known as the Krebs cycle) when oxygen is present (aerobic respiration); when oxygen is lacking, it ferments to produce lactic acid. Pyruvate is an important chemical compound in biochemistry.

Is glycolysis the most efficient?

It arises because while aerobic glycolysis is less efficient than mitochondrial respiration in terms of ATP yield per glucose uptake, it is more efficient in terms of the required solvent capacity.
