Answer :There was enough oxygen in the atmosphere to support a major burst of life on Earth
Explanation:
The Great Oxygen Event marks the time, approximately 2.5 billion years ago, when there was enough oxygen in the atmosphere to support a major burst of life on Earth
For the first half of the Earht's history, there was no oxygen in the atmosphere. It was inhabited only by single-celled organisms.Of those simple life forms, the cyanobacteria may have. evolved a way to take energy from sunlight, and used it to make sugars out of water and carbon dioxide. They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and triggered the evolution of complex life.
An aphid eats from grass which creates High levels of glucose from the process of photosynthesis therefore when the aphid eats the grass the glucose is transferred to the aphid and as a result has a higher concentration of dissolved sugars
Answer:
from glycolysis to electron transport.-glycolytic pathway
NADH and FADH2 are the major electron carrier from glycolysis through the Kreb Cycle to the electron transport chain.
Note-NADH alone transports electron from glycolysis to the Kreb Cycle. while both NADH and FADH2 transport electrons from the kreb'cycle to the electron transport chain.
from citric ac id cycle to the electron transport chain.
as explained above both NADH and FADH2.
The electrons are in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial
Note.
Nicotinamide Adenine Di nucleotide Hydrogen(NADH)
Flavin Adenine Dinucleotide Hydrogen(FADH)
