Answer:
This question lacks options, the options are:
A) Light-capturing pigment molecules in green plants absorb red, blue and violet light but reflect green light.
B) The energy of a photon of light is proportional to its frequency and inversely proportional to its wavelength
C) As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat
D) Captured energy is stored in the molecular bonds of organic molecules, including simple sugars and starch
The answer is:
As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat.
Explanation:
Green plants are capable of synthesizing their own food via a process called photosynthesis. The photosynthetic process uses light energy from the sun to form organic chemicals necessary for the growth and repair of plant tissues.
Plants are able to capture light energy from the sun using their chlorophyll pigment. Out of this captured energy, only a portion of the light energy captured by green plants is available for growth and repair. This is because as light energy is converted to chemical energy (stored in chemical bonds) by metabolic processes, some of the energy is lost as heat.
Answer:
<u>The heavier the hummingbird, the fewer times its wing will beat per second. </u>
Explanation:
There is a negative slope in a graph respective to the components of the x and y axis. Therefore, heavier the hummingbird -> less beats per second.

Answer:
Protein benefit animals because they need this to form new skin cells. They also use protein to grow hair, build muscle tissue etc. Protein also helps the animals to create chemicals like hormones and enzymes that are needed for their normal function.

Answer:
A subunit of Rubisco takes approximately 0.33 s to perform one reaction
Explanation:
The kcat it's a kinetic first order constant that related the properties of the enzyme substrate complexes in a mechanisms and represents the overall first order process of the transformation of the substrate-enzyme complex into product.
Also kcat can be seen as the turnover number of an enzyme, representing the maximum number of substrate molecules that the enzyme can transform into product per time unit and per active site.
If the kcat is 3 s^-1, it means Rubisco can catalyse the transformation of 3 substrate molecules per second.
So, the time that takes a single reaction, should be the inverse of kcat.
To see it more clearly, the time needed for a single reaction is the time observed divided by the number of reactions done during that time.
In other words:
3 reactions ----------- 1 s
1 reaction -------------- x
- x=1 reaction/3 reactions.s^-1 = 1/kcat = 1/3 s ~ 0.33 s
So the time that takes one Rubisco subunit to do one reaction is approximately 0.33 s
