Some organisms do all three parts and some may only do the first part, glycolysis. Explain why larger life forms do the entire p

rocess but much smaller organisms have more leeway in completing it ?

<h2>Answer:</h2>

This is basically because of lack of <u>mitochondria </u>in lower life forms.

<h2>Explanation:</h2>
  • Glycolysis is a Anaerobic(without oxygen) process in which glucose is breakdown in smaller forms without consuming oxygen.
  • So glycolysis is the simplest sourse of energy production and hence it is commonly seen in both lower and higher organisms.
  • However, immediately after finishing glycolysis, the cell will continue either aerobic or anaerobic respiration, this choice depends upon the presence of oxygen and mitochondria as the further process after glycolysis i.e kreb cycle(Citric acid cycle), electron transport chain (ETC) take place in mitochondria with the presence oxygen, and<u> lower organisms lack mitochondria</u> hence they cannot perform process after glycolysis.

Result: Smaller organisms obtain energy only by glycolysis.

An allele is: A. the particular combination of genes for a given trait in a given organism. B. one of several forms of a gene. C
irinina [24]

Answer:

B

Explanation:

According to Mendel, an organism receives two forms of a gene from each parent. This form received by each parent is called an ALLELE. An allele is the variant form of a gene for a particular trait.

For a diploid organism, two copies of genes (alleles) are acquired by an organism. The combination of these alleles from each parent determines the genotype for that gene.

In Mendel's experiments, he discovered that one allele can mask the expression of another for a trait. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. The combination of these alleles, whether two dominant or two recessive called HOMOZYGOUS or one dominant and one recessive called HETEROZYGOUS, determines the phenotype of the organism for that gene.

N.B: There are exceptions to this pattern of inheritance.

Hello.

The answer is 

<span>electron transport chain 
</span>
The stroma is equivalent to the cytosol, it is the aqueous fluid in between thykaloid grana, where carbohydrate formation reactions occur in the chloroplasts of plant cells.

The electron transport chain is found in the thylakoid membrane

You eat a candy bar to get you through a late-night studying session. Your body quickly begins to break down the macromolecules
irga5000 [103]

Answer:

a. First Step: The sugars are broken down to simple glucose molecules and the proteins and lipids are broken down to acetyl-CoA molecules. No energy is produced in this first step.

b. Second Step: Glycolysis converts the glucose to two molecules of pyruvate. Six ATP molecules are produced in this step.

c. Third Step: Oxidation of each pyruvate produces two molecules of acetyl-CoA. Six ATP molecules are produced in this step.

d. Fourth Step: Two acetyl-CoA molecules go through the Krebs (citric acid) cycle. Twenty-four ATP molecules are produced through this process.

e. All of the above steps are part of the break down of the candy bar's macromolecules.
