Answer:
<u>In the mitochondrial matrix</u>
<u></u>
Explanation:
The mitochondria is an organelle within the cytoplasm of the cell. It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into 
(carbon dioxide) and 
(water) to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
(glucose) (oxygen) (carbon dioxide) + (water)
The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.
Answer:
Carbon, Hydrogen, Oxygen, Nitrogen
Explanation:
The most common elements present in organic compounds are carbon, hydrogen, oxygen, and nitrogen. With carbon and hydrogen present, other elements, such as phosphorous, sulfur, silicon, and the halogens, may exist in organic compounds.
In a controlled experiment, the control group is compared with an experimental group.
Explanation:
A set of variables or data is considered as the control group that remains fixed or constant in its normal usual state; while all the other variables or data are identical with this control group, except one independent variable at a time. This is to observe the changes when that one variable is allowed for variations at a time.
This independent variable which undergoes changes is in the experiment group while the remaining constant group is the control group. The dependent variable changes with changes in the independent variable.
By comparing the control group against the experimental group, uncertainty in results are avoided.
The answer is a start codon. An open reading frame is a region of DNA with a span of nucleotides beginning with a start codon (usually ATG) and ends with a stop codon (usually, TGA, TAG, TAA). An open reading frame when translated, codes for a full functional protein hence can be used to predict genes.
The lysosome. It recycles waste from the cell.
