In order to produce the new, 2-carbon acetyl CoA molecule, carbon is taken out of the three-carbon pyruvate molecule produced during glycolysis. Two oxygens from pyruvate are taken up by the eliminated carbon, which leaves the body as carbon dioxide.
Glycolysis and the citric acid cycle are linked by the transition process. The transition reaction changes the two molecules of glycolysis' 3-carbon pyruvate into two molecules of acetyl Coenzyme A, two molecules of carbon dioxide, and two molecules of the 2-carbon molecule.
The cycle converts the acetyl coenzyme A's chemical energy into the nicotinamide adenine dinucleotide's reducing power. The TCA cycle is a component of the broader glucose metabolism, which involves the oxidation of glucose to produce pyruvate, which is then further oxidized and enters the TCA cycle as acetyl-CoA.

how does dna replication between prokaryotes and eukaryotes compare/contrast? choose all that apply.
SIMILARITIES
All prokaryotic and eukaryotic species replicate their DNA in a similar manner. The DNA helicase enzyme is responsible for unwinding the DNA . Polymerases are an enzyme family that facilitates the synthesis of new DNA strands.
Both kinds of organisms also adhere to a replication strategy known as semi-conservative replication. A leading and a trailing strand are created in this arrangement as a result of the distinct directions in which the individual DNA strands are produced.
Small DNA fragments known as Okazaki fragments are produced and subsequently fused to form lagging strands. Both kinds of organisms start new DNA strands with a little RNA primer.
DIFFERENCES
The discrepancies in the size and complexity of the DNA and cells of these organisms are largely responsible for the differences between prokaryotic and eukaryotic DNA replication. A prokaryotic cell has 25 times as much DNA as an ordinary eukaryotic cell.
Prokaryotic cells have a single point of origin, simultaneous replication in two opposing directions, and cytoplasmic replication.
On the other hand, eukaryotic cells use unidirectional replication within the cell nucleus and have numerous sources of origin. Eukaryotes have four or more different types of polymerases, compared to one or two in prokaryotic cells.
Prokaryotic cells replicate far more quickly than eukaryotic cells do. While animal cells like human cells can take up to 400 hours, some bacteria can grow in as little as 40 minutes. Eukaryotes also have a unique method for duplicating the telomeres that are found at the ends of their chromosomes.
Prokaryotes contain circular chromosomes, which eliminate the need for ends. Finally, whereas eukaryotic cells only undergo DNA replication during the S-phase of the cell cycle, short replication occurs almost continuously in prokaryotes.
What is DNA replication?

This type of activity increases heart rate and uses oxygen to provide energy as atp.
Proteins, lipids, and carbohydrates are broken down by oxygen during aerobic exercise to produce ATP. This pathway operates a little more slowly than anaerobic pathways but can produce more ATP since it relies on the circulatory system to deliver oxygen to working muscles. Aerobic, which means "with air," refers to the process by which the body converts oxygen into energy. This usually refers to any exercise session that lasts more than two minutes. "Steady state" exercise is defined as continuous aerobic activity. Anaerobic means "without air" and describes the body's capacity to produce energy.

I and II is the correct answer
What is gel electrophoresis?Gel electrophoresis is a technique used in laboratories to molecularly separate mixtures of DNA, RNA, or proteins. it is a technique used to sort biological molecules according to size. The molecules to be separated are driven through a gel with tiny holes by an electrical field. By putting these molecules in a gel with tiny holes and applying an electric field across the gel, it is possible to separate the molecules. The negatively charged nature of DNA causes it to move toward the positively charged electrode when an electric current is supplied to the gel. Because shorter DNA strands pass through the gel more quickly than longer strands, the fragments are organized according to size.
The following list of fundamental processes for performing gel electrophoresis includes:
Pouring the gel first, getting your samples ready, the gel must be loaded, run, stained, and exposed to an electric field while doing so.
Using a technique called agarose gel electrophoresis, nucleic acid (DNA or RNA) fragments are separated according to their size
1.linearizes the protein
2.II by causing hydrogen bonds in proteins to be broken. gives proteins a general negative charge, limiting the effect of protein size
3.III on gel migration distance. allows the protein to be seen on the gel by intercalating between its amino acids.

What is a Microscope?
A microscope is a device that produces enlarged images of small objects, allowing the observer to get an extremely close look at minute structures at a scale suitable for examination and analysis.
Although optical microscopes are the focus of this article, an image can be magnified using a variety of other wave forms, such as acoustic, X-ray, or electron beam, and received via direct or digital imaging, or a combination of these methods.
The microscope may produce a dynamic image (as with conventional optical instruments) or a static image (as with conventional scanning electron microscopes).
A microscope's magnifying power is a dimensionless ratio that expresses the number of times the object being examined appears to be enlarged. It is usually written in the form 10 (for an image magnified 10-fold),
Photography through a microscope can capture images of interest, a technique known as photomicrography.

In noncyclic photophosphorylation, electrons flow in a one-way path from water to?.
In noncyclic photophosphorylation, electrons flow in a one-way path from water to NADP+.
Photophosphorylation refers to the phosphorylation of ADP to produce ATP during the photosynthesis process. Under aerobic and anaerobic conditions, cyclic photophosphorylation takes place, with sunlight serving as the primary source of energy for living things. The universal energy unit of life is a phosphate molecule called ATP, which is produced by all organisms. In photophosphorylation, protons are pumped across a biological membrane using light energy. This process is mediated by the movement of electrons through an electron transport chain. Proton gradient energy is stored in this way. ATP is produced from ADP and inorganic phosphate as the protons return through the enzyme ATP synthase. The Calvin cycle relies on ATP to help with the production of carbohydrates from carbon dioxide and NADPH.
Cyclic photophosphorylation is the name given to the photophosphorylation procedure that leads to the cyclic movement of electrons during the synthesis of ATP molecules. In this procedure, plant cells only convert ADP to ATP to provide the cells with immediate energy. Non-cyclic photophosphorylation is the name given to the photophosphorylation procedure that causes the electrons to move non-cyclically in order to synthesise ATP molecules using the energy from excited electrons supplied by photosystem II.

What event most directly triggers the release of calcium from the terminal cisternae?.
Action potential propagation down the T tubule most directly triggers the release of calcium from the terminal cisternae.
The action potential travels down the t-tubules and excites the sarcoplasmic reticulum, causing calcium to be released. When calcium binds to troponin, it causes conformational changes in the sarcomere. As a result, the interaction of the sarcomere's thick and thin filaments causes muscle contraction. As the action potential travels down the T-tubules in cardiac muscle cells, it activates L-type calcium channels in the T-tubular membrane. Calcium enters the cell when the L-type calcium channel is activated.
A sarcomere is a myocyte's basic contractile unit. Sarcomeres are made up of two main protein filaments (thin actin and thick myosin filaments), which are responsible for muscular contraction.
