Answer:
B. Enzymes generally catalyze only very specific biochemical reactions.
E. Most enzymes are proteins composed of amino acids
F. The cells of both eukaryotes and prokaryotes all contain enzymes.
G. If the active site of an enzyme is altered, the enzyme is unable to catalyze the biochemical reaction.
Explanation:
Enzymes refers to substances that acts as a catalyst in living organisms. They regulate the rate at which chemical reactions proceed without being altered in the process. Enzymes regulate the biological process that occur within living organisms.
Enzymes catalyze all aspects of cell metabolism such as digestion of food, conservation and transformation of chemical energy and the construction of cellular macromolecules from smaller precursors.
Application of enzymes
1. Industrial application
2. Medical application
1. Enzymes can be used for industrial application such as beer brewing, wine fermentation, bread leavening.
2. Enzyme can also be applied in the medical aspects for killing disease-causing microorganisms, promoting wound healing, and diagnosing some diseases.
Answer:
Given:
Number of colonies on plate = 40
Amount of DNA used for transformation = 100ng
Volume of competent cells used = 100ul
Total volume = 1ml (1000ul)
Volume plated for growth = 200ul
The amount of cells transformed per 1 µg of DNA is called the transformation efficiency
(CFU is colony forming units) => (number of colonies on plate/ng of DNA plated) X 1000 ng/µg = CFU/µg of DNA
Amount of DNA used for plating = 100ng * (200/1000)
= 100ng * (1/5)
= 100/5 = 20ng
Efficiency calculation = 40 colonies / 20ng = 2 colonies/ng
(2 colonies/ng) * (1000 ng/µg) = 2000 CFU/ug DNA
Transformation efficiency = 2000 Transformants / ug DNA
= 2 x 10³ Transformants / ug DNA
Explanation:
Efficiency of transformation is highest in the 100 pg-1 ng range, so Low transformation efficiency could be because of high amount of DNA used for transformation.
Okay so i hope this help but i think its this:
1. chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section
2. light (either natural sunlight or artificial light, like from a light bulb)
3. carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)
4. water (which the plant collects through its roots)
5. nutrients and minerals (which the plant collects from the soil through its roots)
Did researching for you so I hope this helped? :)
I believe it’s the sun
As the sun gives nutrients to the plant
Plant gets satin by animal
Animal gets eaten by animal and so on and the nutrients would be passed on
Answer:
A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. ... Each of these elements is circulated through the biotic components, which are the living parts of an ecosystem, and the abiotic components, which are the non-living parts.
