The molar concentration of ATP in cells is usually 1-10 mM. ATP can be produced through various cellular pathways. The most typical pathway is the oxidative phosphorylation in mitochondria catalyzed by ATP synthase, or the synthesis through photosynthesis in plant chloroplasts. The main sources of ...
Why does the human sperm cell have lots of mitochondria? By Zaira Salvador B.Sc., M.Sc. (embryologist). Mitochondria supply energy to the sperm cells and are responsible for carrying out the process of respiration, necessary to provide the tail (flagellum) with the energy supply that it ...
just mentioned the presence of small microscopic building blocks that were the foundation of all living organisms; these looked like small cells, but this explanation did not mention any of the cell organelles, such as nucleus ormitochondria. In fact, organelles weren’t discovered until much ...
Eukaryotes are any kind of organisms that have complex cells that include mitochondria, nuclei and other cell parts. The three major cell groups are fungi, plants and animals. Many fungi are only related to plants in a superficial way. They might look somewhat like plants and have cell walls...
Do bacterial cells have centrioles? What happens to a plant cell in an isotonic solution? Does mitosis take place in pancreatic cells? During this phase of cell division, the nuclear membrane dissolves, the chromatin coils, and centrioles begin to move to the poles of the cell. a. prophas...
of the ways that feelings of chronic stress, love, hope, and other SEPE factors are transduced into neuroendocrine substances by the hypothalamus, the pituitary, the adrenals, other endocrine organs, the skeleton, other tissues and cells, and, even, mitochondria [69,70,71,72,73,74,75,76,...
Which cells have the most mitochondria in them? Which part of a cell provides structure and gives it its shape? Which structures of the cytoskeleton are found in animal cells but not in plant cells? Which cell organelles are well-developed in secretory cells?
What structure (found in all cells) surrounds the cell membrane and gives support to the cell? Which of the following does not have a membrane? A. nucleus B. ribosome C. mitochondria D. lysosome E. all of the above have a membrane ...
