At room temperature, triglycerides that are solid or semisolid are categorised as fats and are primarily found in mammals. Oils are the triglycerides that are liquid.

Blood lipids (fats) called triglycerides are a type of lipid. Triglycerides are created by your body when it consumes calories that aren't immediately used. In your fat cells, the triglycerides are kept. Triglycerides are subsequently released by hormones for energy in between meals. Having high triglycerides may result from consistently consuming more calories than you burn, especially from foods heavy in carbohydrates (hypertriglyceridemia). Atherosclerosis, or the thickening of the artery walls, which raises the risk of heart disease, stroke, and heart attack, may be exacerbated by high triglycerides. The pancreas can become acutely inflamed when triglycerides are extremely high (pancreatitis).

An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location.

An allele is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution. "The chromosomal or genomic location of a gene or any other genetic element is called a locus.

When genes mutate, they can take on multiple forms, with each form differing slightly in the sequence of their base DNA. These gene variants still code for the same trait (i.e. hair color), but they differ in how the trait is expressed (i.e. brown vs blonde hair).

Translocation mutation is the mutation could affect protein production in other cells of the body

Translocations. When a segment of one chromosome separates and joins another chromosome, the process is known as a translocation. If there is neither genetic material gain nor loss in the cell, this form of rearrangement is referred to as balanced.

A chromosome translocation is characterised by the breakage of a chromosome and its whole or partial reattachment to another chromosome. The Robertsonian and reciprocal translocations are the two main forms of translocations. Two distinct chromosomes have exchanged portions with one another in a reciprocal translocation. An whole chromosome joins another at the centromere in a Robertsonian translocation.

A translocation mutation is a change in chromosome structure and content brought on by a translocation. Many genes can move from one chromosome to another. Such translocation mutations can result in abnormalities in the cell and system growth, development, and operation.

Explanation:

The light-dependent phase of photosynthesis takes place in the thylakoid membrane of the chloroplasts and involves the absorption of light by pigments (primarily chlorophyll) and the conversion of that light energy into chemical energy in the form of ATP and NADPH.

The light-dependent phase of photosynthesis can be further broken down into two stages:

Photochemical stage:

This stage occurs in the thylakoid membrane and involves the absorption of light by pigments, primarily chlorophyll. This absorption causes the pigments to excite, transferring energy to nearby electron acceptors. This energy is then used to pump protons (H+) across the thylakoid membrane, creating a proton gradient.

Electron transport chain:

This stage also occurs in the thylakoid membrane. The proton gradient created in the previous stage is used to drive the production of ATP through the process of photophosphorylation. The protons flow back across the membrane through an enzyme called ATP synthase, which converts the energy of the proton flows into the chemical energy of ATP. Additionally, an enzyme called NADP reductase uses the energy of the electron transport chain to reduce NADP+ to NADPH.

The light-independent phase of photosynthesis, also known as the Calvin cycle or the dark reaction, occurs in the stroma of the chloroplasts. It is called light-independent because it does not require light energy directly. It uses the ATP and NADPH produced in the light-dependent phase to fix CO2 into glucose. The process can be divided into three main stages:

Carbon fixation:

CO2 is taken up by the enzyme RuBP carboxylase/oxygenase (Rubisco) and combined with the five-carbon sugar RuBP to form a six-carbon molecule.

Reduction:

The six-carbon molecule is then broken down into two three-carbon molecules of 3-phosphoglycerate (3-PGA) using the energy from ATP and NADPH.

Regeneration of RuBP:

To continue the cycle, 3-PGA is converted back into RuBP through a series of enzyme-catalyzed reactions. This process consumes ATP but produces glucose as a byproduct. The end products of the light-independent phase are glucose and oxygen.
