Answer:

Glycerophospholipids: Lipids with phosphate-containing head groups. It is a class of lipids that is most abundant in the biological membranes. In this type of lipid, fatty acids are linked by an ester oxygen to the carbon 1 and 2 of glycerol molecule which is the back bone of the molecule.

Cerebrosides:  Fatty acid linked through an amide bond to the sphingosine C(2)-amine. They are one of the most important component  in nerve membrane and animal muscle

Gangliosides: Anionic phospholipids containing one or more sialic acid residue.They are found abundant in the nervous system of animals and human beings.

Sphingolipids: Built on sphingosine. They are also found in the brain and have enigmatic nature.

NAD and FAD work by loading and unloading _________ and _________ during energy transfers.
andrezito [222]

Answer:

Hydrogen and electrons

Explanation:

Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.  

For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.

all of the following are forms of energy a living organism can use except: heat mechanical chemical nuclear
yuradex [85]

All of the following are forms of energy a living organism can use except nuclear energy. Nuclear energy is the use of nuclear reactions that release nuclear energy to generate heat ( thermal energy is being transferred between two objects).Exposure to any radioactive material and energy  is bad because the nuclear energy damages human body and cells.

Explain phloem structure and function, using the following terms: sieve elements, sieve cells, companion cells, girdling, transl
madam [21]

Answer:

Explanation:

Phloem cells are conducting vessels that are found in vascular plant. They are used in the transport of photosynthate produce during photosynthesis from the source of production to other parts of the body.

It consist of sieve elements, which are the conducting vessel that aids transport of sugar round the body. They are very active before maturity at mature they are no longer in use.

Companion cells are used in replacement of sieve element at maturity, they function in metabolism together with the sieve tube Translocation is the transport or movement of sugar round the body.

Girdlings is the removal of the bark of a plant this can inhibit active transport of food.

Non-reducing sugar are monosacharrides such as glucose that are produce and transported round the body of the plant.

P-protein are found in the plants sap usually in large amount in the sieve elements.
