A fully functioning enzyme molecule is fold into a complex
three-dimensional shape and this structure determines the specific type of
molecules it interacts with during a reaction. Each functioning enzyme molecule
has a particular structure to bind <span>with a high degree of specificity to one or a few molecules
and to carry out its function. Therefore, cellular function is directly
associated to its structures.</span>
A production possibility curve shows all maximum possibilities of output for two goods. This curve oftentimes takes the form of a curve to the right. An economy that is coinciding with this curve is said to be efficient. However, if the economy is operating below the curve, then it is said to be inefficient.
<span>During each Krebs cycle, eight reactions should occur. As the reactions happen, the energy currency of the cell, adenosine triphosphate, known as ATP, is made.

<u>Answer:</u>
Gravitational redshift, changes in a planet’s orbital path, gravitational lensing provides the concrete evidence for the general theory of relativity.
<u>Explanation:</u>
- Due to the slowing of time in very 'strong gravitational field' the gravitational redshift occurs.
- The low frequency of the light occurs in the red part when we observe the electromagnetic spectrum.
- The appearance of light is seen slightly shifted to the 'red wavelength'.
- The matter in the galaxies that bends the light from a source at a distance reaching the observer is also a evidence which is termed as gravitational lensing.
Answer: When studying a rock sample, geologists observe the rock's mineral composition, color, and texture.
Explanation:
