The electron acceptor in photosynthesis is NAD+ while in respiration the electron acceptor is NADH. In cellular respiration reaction 36 molecules of ATP are produced in complete oxidation of one molecule of glucose.hotosynthesis is a process in photoautotrophs that converts carbon dioxide into organic compounds in the presence of sunlight. Respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into ATP (adenosine tri phosphate) and waste products.
A: After the prostate gland has been completely removed, any PSA in the blood is produced by prostate cancer cells that have left the prostate gland and spread to other areas of the body. However, sometimes the PSA can appear to be elevated because of a laboratory error.
What is PSA? PSA is one of three major factors that are considered when evaluating a manâs particular case of prostate cancer. PSA stands for Prostate Specific Antigen. The word âspecificâ means that this enzyme is produced only by prostate cellsâwhether normal prostate cells or prostate cancer cells. No other cells (lung, intestine, liver, etc.) make PSA. The purpose of PSA is to keep semen (the white substance ejaculated during sexual intercourse) liquefied.
