Answer:
D: <em>The light-dependent reactions produce ATP and NADPH; the light-independent reactions use energy stored in ATP and NADPH.</em>
Explanation:
<em>Photosynthesis is a biological process during which green plants synthesize glucose using inorganic raw materials such as water and carbon dioxide. I</em>t is a reaction that takes place in an organelle known as chloroplast, and it consists of 2 reactions;
- the light dependent reaction during which light energy is used to split molecules of water and the resulting electron is used to synthesize ATP and NADPH
- the light independent reaction during which the ATP and NADPH produced in light dependent reaction is used to fix carbon dioxide into glucose.
While the light dependent reaction cannot proceed without light availability, the light independent reaction can proceed both in the presence or absence of light.
<em>Hence, the correct option is D.</em>
Answer:
I think you have spelt it wrong, it is cementation
Explanation:
Definition of cementation
1 : a process of surrounding a solid with a powder and heating the whole so that the solid is changed by chemical combination with the powder. 2 : the act or process of cementing : the state of being cemented.
The correct answer is: B) feedback inhibition
This is an example of negative feedback: product of a process reduces the stimulus of the same process. It is the way of regulation in biological systems and the way the organism maintains its homeostasis (internal balance). Negative feedback is present in many biological processes such as regulation of blood sugar, temperature regulation, the actions of some enzymes..
Answer:
A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.
Explanation:
Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.
Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.
When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.
