A chemiosmotic gradient causes hy drogen ions to flow back across the mitochondrial membrane into the matrix, through ATP synthase, producing ATP
What is electron transport chain ?The oxidative phosphorylation process, which produces ATP, is made up of a series of four protein complexes called the electron transport chain that couple redox processes to produce an electrochemical gradient. Both cellular respiration and photosynthesis take place in mitochondria.
The ETC is a group of proteins that are affixed to the inner mitochondrial membrane along with organic molecules. During a series of redox reactions, the electrons move through the ETC and release energy. The protein ATP-synthase uses the energy liberated to create a proton gradient, which is then utilised in chemiosmosis to produce a significant amount of ATP.Learn more about Electron transport chain here:

When a person eats a pieces of chicken, which is filled with protein, it is digested by the body into small nutrients. These small nutrients are then absorbed by cells. The nutrients that came from this piece of meat could be put back together into what kinds of compounds? (has to be at least 2)
Food proteins are digested by enzymatic action. Amino acids are released from these proteins and carried to the consumer's cells where they are used to build new proteins. The nutrients that came from this piece of meat could be put back together into new proteins.
What are proteins and amino acids?
Proteins are polymers with a tridimensional structure needed to accomplish the molecules' functions. These functions depend on the protein, the cell requirements, and the organism that produces them.
Proteins are composed of several amino acids together. These amino acids are monomers.
During protein synthesis, tRNA selects the correct amino acids to build the new protein according to the genetic information provided by mRNA. By working together, mRNA, rRNA, and tRNA arrange amino acids and produce a new protein that will accomplish certain functions.
Some of the amino acids used to build the proteins can not be produced by the organism, so they need to be ingested. These amino acids are introduced to the cell when food is digested and nutrients are absorbed.
The organism breaks down proteins from food into different amino acids that are transported into the cells where they are used.
In the exposed example,
1) the person eats the chicken,
2) the chicken's proteins are digested by enzymatic action,
3) During the chicken's protein digestion, amino acids are released
4) These free amino acids are taken to the person's cells' interior
5) Inside the person's cells, these amino acids are available to be used again by the person's cell.
6) During protein synthesis, tRNA selects the correct amino acids to grow the new polypeptide.

which phrase most accurately describes how the terms cell-mediated immunity and humoral immunity differ?
Cell-mediated immunity is brought about by T cells; humoral immunity is brought about by B cells and antibodies is the most accurate phrase describing cell-mediated immunity and humoral immunity.
The presence of antibodies to a disease in a person's system confers immunity against that sickness. Proteins called antibodies are made by the body to combat or eliminate poisons or pathogens. Diseases are specialized by antibodies.
The main driving force behind humoral immunity, which generates antigen-specific antibodies, is B cells. On the other hand, cell-mediated immunity is predominantly fueled by mature T cells, macrophages, and the production of cytokines in response to an antigen and does not rely on antibodies for its adaptive immunological functions.
The primary distinction between humoral and cell-mediated immunity is the production of antigen-specific antibodies by humoral immunity as opposed to cell-mediated immunity. T lymphocytes, on the other hand, cause apoptosis in infected cells to cause their death.

Only in the blood cells of animals does hemoglobin exist. These claims about hemoglobin are accurate. Red blood cells contain the iron-rich protein known as hemoglobin. Hemoglobin in the blood binds to oxygen as it enters the lungs and delivers it to bodily tissues.
The body lacks the oxygen it needs to function when a person's red blood cells are insufficient or are not functioning properly. Anemia is the diagnosis here. If you have a disease or condition that affects your body's ability to produce red blood cells, your hemoglobin levels may drop. If your hemoglobin level is low, which means your body isn't getting enough oxygen, you'll feel incredibly weak and exhausted.

The pacemakers are thought to be the interstitial cells of Cajal, which are clustered between the layers of smooth muscle tissue. These cells exhibit slow waves, which are rhythmic, spontaneous oscillations in membrane potentials that occur anywhere between three times per minute in the stomach and twelve times per minute in the duodenum. Parasympathetic innervation affects the vagus nerve's reaction. Because of increased vagal activity, which may result in diarrhoea, GI motility is improved.
