what is the role of the electron transppoort chain in forming the h gradient across the inner mitochondiral membrane
The electron transport chain is a set of protein complexes and other molecules that connect protons (H⁺ ions) through a membrane with the transfer of electrons from electron donors to electron acceptors via redox reactions.
It is an exergonic procedure for electron transport. Adenosine triphosphate is synthesized as a result of an electrochemical proton gradient created by the redox reaction energy (ATP). The chain is an energy converter that pumps H⁺ from the mitochondrial matrix to the intermembrane space via the exergonic flow of electrons from NADH to FADH₂. The H⁺ is prone to return across the membrane, dispersing its gradient on its own. And the only regions that allow H⁺to pass through the membrane are the ATP synthases.

which of the following is false about enzymatic reactions? when the temperature is very low, hardly any collision between the enzymes and substrate molecules is possible. when the temperature increases beyond the optimum point, denaturation of enzymes occurs, leading to a drop in enzyme activity. less than and equal to the optimum temperature, any increase in the reaction temperature leads to a decrease in its rate. when the temperature is very low, enzymes are described as being inactive due to low kinetic energy. answer saved
Less than and equal to the optimum temperature, any increase in the reaction temperature leads to a decrease in its rate is not true regarding enzymatic reactions.
Factors affecting enzyme
The reaction that enzymes catalyse receives activation energy from them.
Temperature is one of the elements impacting enzymes. Substrate molecules start to move more quickly as the temperature rises. By increasing the number of substrate molecules that come into contact with the enzymes' active sites, more substrate can bind.
The enzyme's active sites must be free for the velocity to be at its highest level.
The human body uses enzymes to accelerate chemical reactions. Among many other functions, they are crucial for respiration, food digestion, muscle, and neuron activity. There are thousands of enzymes in each cell of the human body. Each cell's use of enzymes aids in facilitating chemical reactions
Proteins that contain amino acids linked together in one or more polypeptides are called enzymes.

Sadie buys 6 postcards and 4 souvenir magnets for $ 16.90. Cruz buys 3 postcards and 3
magnets for $ 10.80. Which system of linear equations can be used to solve for the cost
of each postcard, p, and each magnet, m?
Taking into account the definition of a system of linear equations, the cost of each postcard and the cost of each magnet are 1.25 and $2.35 respectively.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown which when replacing, all the equations of the system are satisfied.
Cost of each postcard and each magnetIn this case, a system of linear equations must be proposed taking into account that:
"p" is the cost of each postcard."m" is the cost of each magnet.You know:
Sadie buys 6 postcards and 4 souvenir magnets for $ 16.90. Cruz buys 3 postcards and 3 magnets for $ 10.80.The system of equations to be solved is
6p + 4m= 16.90
3p + 3m=10.80
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "m" from the second equation:
3m=10.80 - 3p
m= (10.80 - 3p)÷3
m= 3.6 - p
Substituting this expression in the first equation:
6p + 4×(3.6 - p)= 16.90
Solving:
6p + 4×3.6 - 4p= 16.90
6p + 14.4 - 4p= 16.90
6p - 4p= 16.90 - 14.4
2p= 2.5
p= 2.5÷2
p= 1.25
Remembering that m=3.6 - p, you get:
m= 3.6 - 1.25
m= 2.35
Finally, the cost of each postcard is $1.25 and the cost of each magnet is $2.35.

Sickel cell anaemia is caused by a recessive allele. What evidence for this is there in figure 2?
In figure the second generation is unaffected and the third generation is effected which shows that sickel cell anemia is a recessive trait.
What is sickel cell anemia?
A genetic disorder called sickle cell anemia manifests from birth. The changed or mutated genes from your mother, father, or both parents are the root cause of many genetic disorders.Red blood cells in sickle cell anemia sufferers have a crescent or sickle shape.A hemoglobin gene mutation is the cause of this odd form. Red blood cells' hemoglobin component enables them to carry oxygen to tissues all over your body.Red blood cells' sickle shape can cause a number of difficulties. They can get caught inside blood arteries because of their atypical structure, resulting in uncomfortable symptoms.Furthermore, sickle cells age more rapidly than regular red blood cells, which can cause anemia.What are dominant and recessive allele?
Your mother and father each contributed one copy of each gene that makes you up. An allele is a gene's individual copy. Each parent may give you a dominant allele, a recessive allele, or a combination of both.Hence their name, dominant alleles typically take precedence over recessive alleles.Hence, A recessive allele of the hemoglobin gene is responsible for the sickle cell anemia trait.
