Ayoung dog has never had much energy. he is brought to a veterinarian for and she decides to conduct several diagnostic tests. she discovers that the dog's mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal. of the following, which is the best explanation of the dog's condition? a young dog has never had much energy. he is brought to a veterinarian for and she decides to conduct several diagnostic tests. she discovers that the dog's mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal. of the following, which is the best explanation of the dog's condition? his cells cannot move nadh from glycolysis into the mitochondria. his mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane. his cells have a defective electron transport chain, so glucose goes to lactate instead of to acetyl coa. his cells lack the enzyme in glycolysis that forms pyruvate.

The correct answer would be His mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane.

In cellular respiration, glycolysis takes place in the cytoplasm of the cell and converts glucose into 2 molecules of pyruvate. Pyruvate is then transported into the mitochondria for further oxidation.

It is transported into the mitochondria with the help of transport protein pyruvate translocase where it is decorboxylated to produce acetyl-CoA. This acetyl-CoA then enters the Krebs cycle to produce ATP (adenosine triphosphate) with the help of oxidative phosphorylation, electron transport chain and chemiosmosis.

In absence of this transport protein, the cell can not completely oxidize the glucose or carbohydrate. It switches to the metabolism of fats and amino acids in order to meet the energy demands of the cell.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
