Answer:

A special characteristic of one living creature is to grow, to do metabolic processes to react to adapt and to reproduce.

Explanation:

The purpose of human life is to be aware of the existence, to understand existence,  to be responsible and to enjoy.

Why are we chosen to live in this world it is not known. There are theories that RNA plays an important part in this. The process that many forms of life developed through history by mutation and natural selection. And the most common answer to a question why are we here is the simple process of evolution.

List and describe three factors that affect how quickly enzymes can work to catalyze reactions
Lilit [14]

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

The pKa of an acid depends partly on its environment. Predict the effect of each of the following environmental changes on the p
Galina-37 [17]
The pKa represents the pH of the medium at which the zwitterionic amino acid assumes most stable ionic form due to structural stabilization. As the pKa is dependent upon the environmental factors of the solution around the amino acids, a change in their structure and localization can cause change in the pKa of the protein. Thus, the answers can be found as below:

Part A: Decrease (As the lysine is basic in nature, it will tend to stabilize the electrostatic interaction and weak interactions between the acidic amino acids and hydrogen bonds in the viscinity, thus lowering the pH and hence pKa of the protein)

Part B: Increase (As the carboxyl group is acidic in nature, removal of it will tend to increase the pKa since the basic amino acids will tend to accumulate more negative charge in their viscinity)

Part C: Increase (As glutamic acid is an acidic amino acid, its shift from outside to a non-polar site will prevents its ionization and hence the pKa will tend to shift from slightly acidic to slightly basic, hence increase)

Analyze this molecule and select all of the true statements below. Check All That Apply This molecule is adenosine triphosphate.
ira [324]

Answer:

ATP, is a molecule  called adenosine triphosphate.

This molecule takes part in coupled reactions:This molecule participates in a large number of biochemical reactions, this molecule is the energy contribution of reactions, it appears in the Krebs and glycolysis cycle.

This molecule is a type of nucleotide.

ATP is a nucleotide formed by three phosphate groups and an adenosine. The nucleotide is adenine with three energy-rich phosphate groups.
