the interactions between two proteins such as an antibody and an antigen or a hormone and its receptor are quite strong despite the fact that these interactions consist of relatively weak noncovalent bonds. how can this be?
This observation is explained by the concept of molecular complementarity.
Concept of molecular complementarity.
Because there are so many noncovalent interactions happening when proteins, such as an antibody and an antigen, match up in a way that creates many noncovalent bonds, even weak noncovalent bindings can effectively produce strong interactions between two proteins.
When the structures of molecules or macromolecules fit together, physical, non-covalent interactions cause them to associate reversibly with one another. This is known as molecular complementarity.

The layer where most of the x-rays & gamma rays from the sun are absorbed and the ionosphere is found is Thermosphere.
The layer of incredibly rare air above the mesosphere is referred to as the thermosphere. The high-energy X-rays and UV radiation from the Sun heat the thermosphere to hundreds or perhaps thousands of degrees. We would, however, feel quite cold in this stratum due to how thin the air is.
In many ways, the thermosphere is more like outer space than the atmosphere. Actually, lots of satellites orbit the planet inside the thermosphere! Variations in the energy coming from the Sun have a significant impact on the temperature and height of the top of this layer.
The ionosphere is not a discrete layer. The ionosphere, on the other hand, is a collection of places in some mesosphere and thermosphere where high-energy radiation from the Sun has jarred electrons free of their parent atoms and molecules.

what are the two primary ways percipitation passes through the water cycle
The two primary ways through which the precipitation passes through the water cycle are Rain and Snow.
What is Water Cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle. The amount of water on Earth stays relatively constant over time, but how it is divided up into the major reservoirs of ice, fresh water, saline water (salt water), and atmospheric water varies based on a variety of climatic factors.
Evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow are some of the physical processes by which water travels from one reservoir to another, such as from a river to the ocean or from the ocean to the atmosphere. As a result, the water transforms into liquid, solid (ice), and vapour.
The energy exchange that takes place during the water cycle causes temperature fluctuations. Water evaporation cools the atmosphere by absorbing energy from its surroundings. It releases energy and heats the surroundings when it condenses. The climate is affected by these heat exchanges.

enzymatic activation of pyruvate kinase increases cytosolic oxaloacetate to inhibit the warburg effect
Enzymatic activation of pyruvate kinase increases cytosolic oxaloacetate to inhibit the Warburg effect is a research paper written by Elizabeth K Wiese, Sadae Hitosugi, Sharon T Loa, Annapoorna Sreedhar, Lindsey G Andres-Beck, Kiran Kurmi, Yuan-Ping Pang, Larry M Karnitz, Wilson I Gonsalves and Taro Hitosugi.
What is the abstract?The PKM2 paradox in the Warburg effect is a phenomena whereby lactate generation is lowered following pharmacological stimulation of the glycolytic enzyme PKM2 or expression of the constitutively active PKM1 isoform in cancer cells. Here, we demonstrate that oxaloacetate (OAA) inhibits human lactate dehydrogenase A competitively, and that increased PKM2 activity boosts the de novo production of OAA by glutaminolysis, inhibiting LDHA in cancer cells. Furthermore, we demonstrate how the contradictory relationship between increased PKM2 activity and lower lactate concentration in cancer cells treated with a PKM2 activator was abolished by substituting human LDHA with rabbit LDHA, which is highly resistant to OAA inhibition. In addition, rabbit LDHA-expressing tumors were more resistant to the PKM2 activator than human LDHA-expressing tumors in mice.
