1. Compare and contrast ATP and NADH.
Leokris [45]

Answer:

Glycolysis produces 4 ATP molecules, giving it a net gain of 2 ATP molecules. The four high energy electrons that are removed by glycolysis are picked by an electron carrier called NAD. NAD becomes NADH.As it spins it grabs an ADP molecule and attaches a phosphate, forming high energy ATP.

Explanation:

Both NADPH and ATP are phosphorylated compounds, both are very important catabolic as well as anabolic processes. To explain the difference, their respective functions/roles in biochemical processes should be described along with relevant chemical properties.

ATP (Adenosine triphospahte) is called an energy rich molecule because of the large negative free energy of its hydrolysis (And has nothing to do with high bond energy).

30.5 kilo Joules or 7.3 kilo calorie energy is liberated after hydrolysis of one ATP molecule to form ADP (Adenosine diphosphate) and phosphate.The reaction is almost irreversible

Taxonomic classification involves sorting a given organism into progressively more specific levels of categories until you find
Novay_Z [31]

Answer:

Kingdom --> phylum/division --> class --> order --> family --> genus --> species

Explanation:

The formal system of classification used in taxonomy was introduced by a Swiss scientist named Carolus Linnaeus.

He first split living things into a general category called KINGDOM.

- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).

- Each phylum or division is broken down into CLASSES.

- Each class is broken down into ORDERS

- Orders into FAMILIES,

- Families into GENUS

- Genus into SPECIES

Thus, the system of classification from highest (most general category) to the lowest level is as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species
