Cyanobacteria which is a type of algae. It conducts photosynthesis and without it there may not have been life today because they didn't need oxygen to survive and in order to have oxygen there had to have been some form of life...

Bacteria is the organism that scientists believe was responsible for changing the composition of the early atmosphere. It changed the atmosphere by using energy from the Sun for photosynthesis, and released oxygen as a byproduct. The change on the atmosphere was so important because it added more oxygen to our atmosphere, which brings us to our current atmosphere composition of 21% oxygen and 78% nitrogen.

Hope this helps!

The type of bond that joins monosaccharides and is easily digested by enzymes in the human intestine is a __________. delta bond
timurjin [86]

Answer: alpha bond

Explanation:

The carbohydrates popularly called sugars are energy nutrients formed by carbon, hydrogen and oxygen atoms. It is the main energy source of the man and also has a structural or plastic role (formation of parts of cells such as the cell wall, or tissues, such as the exoskeleton chitin of the insects and crustaceans - crab). The small intestine's main mission is to complete the digestion of the chyme. In its passage through the duodenum, it suffers the action of pancreatic and intestinal juices and bile. In fact, it is in the duodenum that most digestive secretions are produced. The foods complexes are thus transformed into simple elements, easily assimilable by the body.

Enzymes are protein catalysts responsible for most of the chemical reactions of the organism, is found in all tissues. Amylase acts in the intestine hydrolyzing glucose polymers (starch, amylopectin, and glycogen). The bonds that hold the monosaccharides together and which are easily digested by pancreatic amylase in the intestine are known as alpha bonds. Some examples of sugars that have alpha bonds are sucrose, maltose, and starch.

A researcher claims that the synthesis of ATP from ADP and inorganic phosphate (Pi) is essential to cellular function.
ch4aika [34]

Answer: A B C

Explanation:

The synthesis of ATPS takes place in the mitochondrial and chloro plasts of cells.It is an exergonic reaction that involves the use of energy released from influx of protons to for the catalysis of in organic phosphate and ADP by enzyme ATP Synthase in the stroma and matrix of chloroplasts and mitochondrial respectively.

The 3 bonds that connected phosphate ions to ADP to form ATP must be broken down(hydrolysis) with water to release the energy for biochemical activities of the cells.

The first bond hydrolysis releases first phosphate and ATP changed to ATP,

The second bond releases breakage changed the ADP to AMP with the release of more energy.
