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

When examining the transmission of phenylketonuria (PKU), a recessive trait, we can clearly identify the __________ when a child

postnew [5]

When examining the transmission of phenylketonuria (PKU), a recessive trait, we can clearly identify the genotype when a child is afflicted with PKU. For the child not afflicted with PKU, we can only identify the phenotype, as the child may or may not be a carrier.

An organism's genotype is its particular aggregate of alleles for a given gene. So, for example, in the pea plants above, the feasible genotypes for the flower-color gene were pink-purple, red-white, and white-white. The phenotype is the bodily manifestation of an organism's allellic combination (genotype).

Someone's genotype is their precise sequence of DNA. Greater specifically, this term is used to consult the two alleles someone has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's scientific presentation.

An example of a monosaccharide is ________.

Bad White [126]

Answer:

All of the above.

Explanation:

Monosaccharide may be defined as the sugars that are not further hydrolyzed or that do not give further sugars on hydrolysis. These monosaccharides are sweet in taste.

Glucose, galactose and fructose are monosaccharide sugars as they cannot be hydrolyzed further to give more sugars. These are colorless and water soluble sugars.

Thus, the correct answer is option (4).

Once pollen lands on the stigma, it forms a pollen ____________________ down through the long_____of the pistil [the female repr

xz_007 [3.2K]

Answer:

1. Pollen tube

2. Style

3. Ovary

Explanation:

This process is describing the process of POLLINATION, which is the transfer of pollen grains from the anther of a male flower (androecium) to the stigma of the female flower (gymnoecium). After pollination i.e. the pollen has landed on the sticky stigma, the pollen grows out a tube called POLLEN TUBE.

The pollen tube extends through the STYLE of the female flower called PISTIL to the OVARY. The ovary is the reproductive part of the female flower that produces the ovules, which the sperm in the pollen is about to fertilize.
