Oxygen is required for aerobic respiration. This reaction produces ATP (universal currency for energy) which our bodies use to survive. Without oxygen much less ATP is produced, as aerobic respiration cannot occur in the lack of oxygen. ATP can be formed by anaerobic respiration, in the lack of oxygen, but this produces far far fewer molecules of ATP. This also produces lactic acid causing us to become fatigued and tired. Thus oxygen is crucial to produce the maximum amount of ATP possible.
Glucose is the main molecule which is respired by our bodies to produce ATP/ energy, which our bodies use to survive. Oxygen and glucose react in the mitochondria to make ATP (release energy.) It therefore, is called a respiratory substrate.
Note: I'm avoided talking about the exact phases of respiration as it is usually not covered till college/ A level standards. If you would like to know exactly which reaction requires oxygen and how it's used (i.e. the stages of respiration) don't hesitate to ask.
Answer;
- Endotoxin
Explanation;
-Endotoxins are part of the outer membrane of the cell wall of Gram-negative bacteria. Endotoxin is invariably associated with Gram-negative bacteria whether the organisms are pathogenic or not.
-They are large molecules consisting of a lipid and a polysaccharide composed of O-antigen, outer core and inner core joined by a covalent bond; they are found in the outer membrane of Gram-negative.
Answer:Folic acid
Explanation:
Folic acid is a vitamin that is used in reactions that transfer single-carbon units. The vitamin also helps reduce the risk of birth defects such as spina bifida and cleft lip. Women of child-bearing age should consume the recommended amount of this vitamin.
<span>Answer : spores, which grow into
a gametophyte<span>
</span><span>A
sporophyte produces spores therefore those plants that have spores is called
sporophyte. A sporophyte is a type of a diploid organism so, which means
that meiosis must occur in order to be able to produce haploid cells containing
half number of chromosomes. Meiosis in sporophyte occurs in an area called
sporangia. The spores that are being created inside sporangia shall be release
into the air. Mitosis is expected to take place on a single haploid spore in
order to be a multicellular gametophyte.</span></span>
Answer:
Observation and measurements recorded during an experiment. All the variables that are kept the same throughout the experiment so they will not affect the results of the experiment. independent Variable. The variable which the experimenter changes so that he/she can observe the results of the experiment.
