Answer:

anaerobic organisms do not require the presence of oxygen to produce energy in form of ATP, while aerobic organisms require oxygen

Explanation:

Anaerobic organisms produce energy by glycolysis, which is a metabolic pathway that produces ATP by transforming glucose to lactate when oxygen (O2) is limited. Glycolysis produces two (2) molecules of ATP per glucose molecule. Moreover, when O2 is available, aerobic organisms produce ATP by cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. Cellular respiration is able to produce thirty-eight (38) molecules of ATP per glucose molecule, thereby being more efficient than glycolysis.

How would the absence of gravity affect the formation of planets
Cerrena [4.2K]

Answer:

The rocks and debris would never accrete into a planet.

Explanation:

Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force, the rocks and debris would not come together to form a clump. So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet. So,  we can say that in the absence of gravity, the rock and debris would never accrete into a planet.

Solid tumors are clusters of cancer cells and often contain blood vessels. When molecule B binds to the wild-type Brec protein i
Agata [3.3K]

The molecule C-P phosphorylates and thus activates D, whereas Kinase D amplifies cellular signaling by phosphorylating many substrates. In this case, it is expected to observe kinase D overexpression in Brec-MUT cells.

<h3>Cancer, phosphorylation and signaling pathways</h3>

Cancer can be defined as a multifactorial disease, which is often associated with uncontrolled cell growth.

Cancer signaling may be associated with defective pathways such as, for example, a mutated kinase protein that affects normal downstream molecular cascades.

A kinase is a specific protein that acts to phosphorylate specific cellular substrates, thereby activating/deactivating a particular signaling pathway.
