How did the carbon atom get into cellular respiration

2 answers:

Carbon atoms are converted into metabolites like acetic acid, lactic acid, aldehydes, etc via the action of different bacteria. In the process of fermentation or cellular respiration, carbon atoms are cleaved into three carbon molecule called pyruvate then eventually forming into metabolites.

During cellular respiration the molecule takes in oxygen and glucose. In glycolysis, the six-carbon sugar, glucose, is broken down into two molecules of three-carbon molecule called pyruvate.

The wild-type form of a gene encodes a protein of length 100 amino acids. A mutant allele has a UAA (instead of the wild-type, C

Orlov [11]

Answer:

48 amino acids

Explanation:

The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.

45. The main product(s) of the light-independent ( dark reactions ) of photosynthesis is/are

alexira [117]

Answer:

C. glucose

Explanation:

Dark reaction takes place outside the thalakoid membrane (stroma and cytoplasm). During dark reactions, energy is released from ATP and NADPH to fix carbon dioxide into <em><u>glucose</u></em>.

Option A and B are not correct because they are produced during light reactions. Likewise, chlorophyll is the part of cell and is not prepared during light or dark reactions at all.

Will award 70 points!

Verizon [17]

Answer:

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

15 POINTS!! What is the purpose of a dichotomous key? (Select all that apply.)

postnew [5]

The purpose of a dichotomous key is to identify organisms

Explanation:

A dichotomous key is a kind of a tool that guides to classify and identify different organisms.

This key as the name indicates - dichotomous- consists of two parts or options to identify a species.

The method utilizes a series of questions/answers with two possible outcomes.

Taxonomically, a dichotomous key is used to basically identify a species or an organism by its scientific name.

All of the natural elements like the plants, animals, birds, etc are identified using this key.

Types of dichotomous key includes nested, linked, branching tree etc.
