Study Notes
Male Reproductive System
- The epididymis temporarily stores sperm produced in the testes.
- Leydig cells primarily function to produce testosterone, essential for male sexual development and functions.
- Approximately 1,500 sperm cells are produced by the male reproductive system each second, translating to millions daily.
Female Reproductive System
- The endometrium is responsible for the monthly shedding of the uterine lining during menstruation.
Sperm Development
- Sperm cell development takes approximately 64 to 72 days to reach maturation.
Hormonal Regulation
- The production of testosterone by Leydig cells is regulated by luteinizing hormone (LH).
Nervous System Functions
- The parasympathetic nervous system promotes rest and recovery after a crisis, maintaining normal bodily functions.
- The sympathetic nervous system prepares the body for 'fight or flight' responses during crises.
DNA and RNA
- The primary function of DNA is to store and transmit genetic information.
- The order of the central dogma of protein synthesis is DNA → RNA → Protein.
- During DNA replication, helicase enzyme breaks the hydrogen bonds between nitrogenous bases, allowing strands to separate.
- The primary difference between DNA and RNA lies in their nucleotide composition: DNA contains deoxyribose, while RNA contains ribose.
Protein Synthesis
- Translation is the process of producing proteins directly from RNA instructions.
- tRNA (transfer RNA) transports amino acids to the ribosome to help synthesize proteins.
- The codon AUG serves as the start codon in protein synthesis, signaling the beginning of protein production.
Evolution
- According to Charles Darwin's theory of evolution, organisms acquire new traits through natural selection, where advantageous traits enhance survival and reproduction.
Role of DNA Replication
- DNA replication is crucial for cell division, ensuring that genetic information is accurately copied and passed to daughter cells.
