Answer:
The correct option is lactic acid energy system
Explanation:
The option chosen as the correction is "b lactic acid energy system" since in sprint races the distance is short, or relatively short as in this case they are two and a half blocks or 220mts, in these short distances the contraction Muscle is of high potential, activates the red muscle fibers that are the tools that specialize in explosive contraction with few demands on oxygen, a difference from the white ones that are the opposite (these work at a medium concentration of oxygen and low contractions sustained power over time).
Red muscle fibers contract very powerfully and with few oxygen requirements, but this implies a higher production of lactic acid for the athlete, because this acid is the product of anaerobic contraction.
Muscle contraction with few partial pulsations of oxygen generates accumulated sorts between the muscle fibers of lactic acid, and is the well-known post-exercise pain of athletes.
Athletes who train for sprint challenges also consume glucose rapidly consumed to improve the effectiveness and power of contraction.
Furthermore, the oxygen requirements are few because, as it is a high potency and short duration activity, it does not give the body time to supply the partial oxygen pressures that are completely needed.
The answer is B. Paleozoic
This era was the first era where insects, amphibians, and reptiles roamed the Earth.
Hope this helps!
Explanation:
B. Lactic acid is produced from lactobacilli as the starter undergoes fermentation
Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate (pyruvic acid) is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation. In lactic acid bacteria, the pyruvate produced is directly transferred to lactate (a form of lactic acid) producing NAD+.
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).
Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.
This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...
- Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
- The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
- The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
Within cells, aerobic respiration may not occur due to several factors:
- - a lack of inorganic, final electron acceptors
- -incomplete or lack of a complete electron transport system
- -missing genes for enzymes within the Kreb's cycle
