refer to the flowchart. which phrase best fills in the missing information in the flowchart? chemical energy stored in electron transport proteins chemical energy stored in oxygen chemical energy stored in a proton concentration gradient chemical energy stored in atp synthase

Answers

Answer 1

The flowchart's missing information refers to the manner in which chemical energy is stored after the electron transport chain. The term "chemical energy stored in a proton concentration gradient" best fills in the blanks in the flowchart.

The electron transport chain (ETC) is the final stage of cellular respiration, which is a metabolic process that transforms glucose and other organic molecules into ATP energy (adenosine triphosphate). During the ETC, electrons are transported via a sequence of protein complexes in the inner mitochondrial membrane, eventually generating a proton gradient across the membrane.

Because electrons given to the ETC are utilised to push protons (H+) from the mitochondrial matrix to the intermembranous space, a larger concentration of protons is produced in the intermembranous space than in the matrix. The protons then return to the matrix through an ATP synthase enzyme, which uses the energy produced by the flow to fuel the synthesis of ATP from ADP (adenosine diphosphate) and inorganic phosphate.

As a result, chemical energy is stored in the ETC in the form of a proton concentration gradient, which is formed by pumping protons across the inner mitochondrial membrane. ATP synthase then uses this stored energy to power the creation of ATP, the fundamental energy currency of cells.

Why are the effects of genetic drift more pronounced in smaller populations?

Answers

The effects of genetic drift more pronounced in smaller populations because of  stochastic sampling error, small populations lose genetic diversity faster than big populations (i.e., genetic drift).

The population size, formally the effective population size, is connected to the population's drift strength and the risk of inbreeding. Furthermore, because the population is smaller, individuals are more likely to breed with close relatives.

Individuals in confined populations are more intimately linked to each other than individuals in prior generations. In a hypothetical population of only four individuals, for example, if two pairings each had two kids  the offspring must either mate with a sibling, a parent, or an individual from the other couple.

If they pick the non-sibling/non-parent option, all kids in the third generation must mate with people who have the same grandparents or abstain from reproducing. Although this is an extreme example owing to the extremely small hypothetical population, the same patterns and dynamics may be found in bigger - albeit still small - populations.

Although the method of genetic diversity loss due to inbreeding and drift differs, the impact on populations are similar. Inbreeding and drift both limit genetic variety, which has been linked to an increased risk of population extinction, a slower population growth rate, a worse capacity to respond to environmental change, and a lower ability of released individuals to survive and reproduce in the wild.

Answers

The double coiled, "staircase" shape of DNA is called a double helix.

DNA, or deoxyribonucleic acid, is a long, thread-like molecule that contains the genetic information that is passed down from parents to offspring.

The double helix refers to the specific shape of the DNA molecule, which consists of two long strands that wind around each other in a twisted ladder-like structure.

The individual strands of the DNA molecule are made up of nucleotides, which are composed of a sugar molecule, a phosphate group, and a nitrogenous base. The nitrogenous bases, which include adenine, thymine, guanine, and cytosine, are the specific chemical units that carry the genetic information in the DNA molecule.

The double helix structure of DNA is important because it allows the molecule to be tightly packed into the cell nucleus, while still remaining accessible for processes such as replication and transcription. The discovery of the double helix structure of DNA is considered one of the most important scientific discoveries of the 20th century, and it has had a profound impact on fields such as genetics, medicine, and biotechnology.

there are two active sites in the functional enzyme (one in each subunit), but only one substrate molecule can be processed at a time. why is this? be sure to appropriately cite your source.

Answers

The reason why only one substrate molecule can be processed at a time in an enzyme with two active sites is due to a phenomenon called cooperativity.

Cooperativity is a process by which the binding of one substrate molecule to one active site of the enzyme affects the properties of the other active site. In the case of enzymes with two active sites, binding of a substrate molecule to one site results in a conformational change that makes it easier for another substrate molecule to bind to the second active site. However, this conformational change also results in the second active site being less efficient at catalyzing the reaction. Therefore, the overall efficiency of the enzyme is optimized for processing one substrate molecule at a time.

The lock-and-key model and the induced-fit model are two enzyme action models that explain both enzyme specificity and catalytic activity.

Emil Fischer hypothesized the Lock and Key model of enzyme action in 1899. According to Fischer, enzymes are highly specific to the substances with which they react. The substrate(s) bind to the enzyme at the active site, resulting in the formation of an enzyme-substrate complex.The enzyme speeds up the chemical reaction. This reaction can be a synthesis reaction (bond formation) or a digestion reaction (breaking bonds to form new substances).The enzyme releases the reaction's product(s). After completing a reaction, an enzyme can be reused. The Induced Fit model of enzyme structure provides a more accurate description of enzyme structure.Daniel Koshland proposed the Induced Fit model in 1958. The active site, according to Koshland's hypothesis, is shaped similarly enough and has specific chemical properties that attract a substrate to bind.

explain why there is no gene flow in reproductive isolation. determine why reproductive isolation is a prerequisite for speciation to occur.

Reproductive isolation is the inability of individuals in a population to reproduce offspring.

This can happen due to various factors such as geographic barriers, temporal isolation, behavioral differences, and genetic incompatibilities.

If two separate population are isolated in two particular geographic area, then visibly there will be no gene flow. That means that the genetic material of the two populations are not mixing up.

This then result in the formation of a hybrid or new species. This process is called speciation.

When the population migrates they may introduced to new genetic variations into a population. This can be one of the main reason for gene flow.
