What process involves Chemiosmosis?
The actual production of ATP in cellular respiration takes place through the process of chemiosmosis (see Chapter 4). Chemiosmosis involves the pumping of protons through special channels in the membranes of mitochondria from the inner to the outer compartment.
Where does meiosis occur in the body?
Meiosis or reduction division occurs during gametogenesis in the formation of gametes (sperm and ova). Meiosis occurs in the testes and ovaries of males and females, respectively, in the primordial germ cells.
Where does mitosis occur in the body?
Mitosis occurs in the cells for growth and for repair and replacement of the damaged and dead cells. Mitosis occurs actively in the bone marrow and skin cells to replace cells, which have a limited lifespan.
Does meiosis occur in the uterus?
In females, oogenesis and meiosis begin while the individual is still in the womb. The primary oocytes, analogous to the spermatocyte in the male, undergo meiosis I up to diplonema in the womb, and then their progress is arrested.
Does meiosis occur in fallopian tubes?
Second meiotic division in female egg do not get completed before the entry of sperm. Hence, second meiotic division takes place after ovulation, inside fallopian tube. As the sperm head enters egg cytoplasm, second meiotic division proceeds to its final phase, giving out a second polar body.
Where does chemiosmosis take place in photosynthesis?
the chloroplasts
Yes, chemiosmosis occurs in photosynthesis and respiration. During photosynthesis, chemiosmosis occurs in the chloroplasts, whereas during respiration, chemiosmosis occurs in the mitochondria.
Where does electron transport chain occur?
mitochondria
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
Where does meiosis occur in ovule?
In an ovule, meiosis occurs in the megaspore mother cell.
Where is meiosis occurs in man and woman and explain some differences between meiosis in both?
In human males, meiosis occurs in the seminiferous tubules of the testicles while in females, it occurs in cells called as oogonia. In males, meiosis occurs at puberty while in females it occurs right at birth.
Where does mitosis occur in females?
ovaries
In animals this occurs in the gonads (ovaries in females; testes in males). In plants this occurs in the archegonia in females and in the antheridia in males.
Where do mitosis and meiosis occur in the body?
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.
