Answer:
transport of protons (H+) from low concentration in the mitochondrial matrix to high concentration in the mitochondrial intermembrane space
Explanation:
atpase pump can also be called atp synthase. this enzyme catalyses atp formation from adenosine diphosphate and phosphate. it has f1, stalk and f0 components. 3 positive hydrogen ions go through to make 1 adenosine triphosphate molecule. oxidative phosphorylation has to do with the loss of electrons. there would be electrons loss from NADH to FADH2. Cytochromes carries them through different series of transferases from I to IV and while on this positive hydrogen ions are released into mitochondrial matrix
positive hydrogen ions are moved back to lumen through adenosine triphosphate channels. a process called chemiosmosis. the pro
Answer:
The correct answer is "building gradients of substances across the outer cell membrane"
Explanation:
Building gradients of substances across the outer cell membrane is a form of diffusion in which substances move across cellular membranes based on there independent gradient. This form of movement is a type of passive transport because it does not require the use of ATP for transport. The building gradients of substances across the outer cell membrane requires diffusion and does not require the use of ATP.
Movement of vesicles along cytoskeletal tracks requires individual vesicles to be transported by there respective motor proteins along the cytoskeletal tracks. These motor proteins require ATP to move these vesicles. Also, the phosphorylation of a motor protein in the cytosol requires one phosphorus molecules from ATP.
Transport of protons (H+) from low concentration in the mitochondrial matrix to high concentration in the mitochondrial intermembrane space is a description of the "hydrogen pump" that occurs in the electron transport chain. When hydrogen ion pump occurs, the hydrogen ion gets flown back through a ATP molecule.
A set of identical twins are together in an introductory biology class. The unit of study is DNA and its structure. The teacher describes the structure of DNA and its role in gene expression over the course of the lesson. Which components of the structure and expression of DNA would be identical for these particular twins that account for their similar appearance? Select ALL that apply. A) The timing of the DNA replication is identical for all cells in these students. B) The environmental influence of gene expression is identical for both students. C) The alleles that are carried on the chromosomes are identical for both students. D) All of the genes carried on the DNA are always expressed for both of these students. E) The order of the bases on the interior of the DNA molecule is identical.
In identical twins, alleles are identical and the order of the bases on the interior of the DNA molecule is identical (Options C and E). It is because genetic material is identical.
What are identical twins?Identical twins refer to individuals produced by the same zygote cell, i.e., they are monozygotic twins.
Since these individuals are produced by the same zygote cell, their genetic material (DNA) will be identical.
Identical twins are useful to understand the exact role of genetics and environment in a given phenotypic trait.

which structure inside the cell holds the digestive enzymes that break down the carbohydrates
Answer:
The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

Cyanobacteria, also known as blue-green algae, are a kind of bacteria found in many lakes. These organisms make their own food through photosynthesis. Small animals including mayfly larvae eat the cyanobacteria, and small fish such as yellow perch eat the larvae. The small fish provide food for larger fish, such as walleye.
Describe a model you could use to show the transfer of energy within the lake ecosystem. In your description of your model, make sure you include the position of each organism identified in the paragraph.
Answer:
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.
Many Proterozoic oil deposits are attributed to the activity of cyanobacteria. They are also important providers of nitrogen fertilizer in the cultivation of rice and beans. The cyanobacteria have also been tremendously important in shaping the course of evolution and ecological change throughout earth's history. The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras. Before that time, the atmosphere had a very different chemistry, unsuitable for life as we know it today.
The other great contribution of the cyanobacteria is the origin of plants. The chloroplast with which plants make food for themselves is actually a cyanobacterium living within the plant's cells. Sometime in the late Proterozoic, or in the early Cambrian, cyanobacteria began to take up residence within certain eukaryote cells, making food for the eukaryote host in return for a home. This event is known as endosymbiosis, and is also the origin of the eukaryotic mitochondrion.
Because they are photosynthetic and aquatic, cyanobacteria are often called "blue-green algae". This name is convenient for talking about organisms in the water that make their own food, but does not reflect any relationship between the cyanobacteria and other organisms called algae. Cyanobacteria are relatives of the bacteria, not eukaryotes, and it is only the chloroplast in eukaryotic algae to which the cyanobacteria are related.

Which statement summarizes the relationship between chromosomes,DNA, and genes
Answer:
The accurate answer to this is:
D.Genes use DNA code to manufacture proteins for chromosomes.
Explanation:
Genes use DNA code to manufacture proteins for chromosomes.
What are chromosomes?
The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule.
Chromosomes are found in the nucleus of cells in both plants and animals, including humans. There are 46 chromosomes in all, including 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY).
Children receive half of their chromosomes from their mother and half from their father because each pair comprises two chromosomes, one from each parent.
Therefore, Genes use DNA code to manufacture proteins for chromosomes.
