Answer:
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:
There is no diagram in this question, however, the question can be answered based on general understanding.
Light energy is converted to chemical energy by PLANTS (GRASS) i.e from the sun to grass
Explanation:
This question is trying to depict a food web or chain of organisms feeding on one another in order to obtain energy. However, in this process, only one organisms amongst the list of organisms is capable of converting LIGHT energy to CHEMICAL ENERGY.
This organism is called a PRODUCER and it is the GRASS (plant). Green plants like the grass in this question are autotrophs i.e. are capable of producing their own food via the process of PHOTOSYNTHESIS. In this process of photosynthesis, plants capture light energy from the sun and convert it to chemical energy stored in sugars.
Answer:
D) receptor tyrosine kinases
Explanation:
Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).
Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).
Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism
Answer:
75% = 
= 0.75
20% = 
= 0.20
0.8% = 
= 0.008
Explanation:
75% means "75 for every 100". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 75% would become 0.75
20% means "20 for every 100". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 20% would become 0.20
0.8% means "0.8 for every 100", but it's easier to understand if you write it as "8 for every 1000". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 0.8% would become 0.008
Hope this helps.
