Answer
The correct sequence is given below.
Explanation:
A. NAD+ (It recieves electrons directly from substrate in glycolytic as well as Citric acid cycle reactions)
B. Oxidoreductase (It is present as complex I termed NAD+-CoQ oxidoreductase. It receives electrons from NADH)
C. Quinone (It is present as Ubiquinone in complex III of Electron transport chain. It receives electrons from NADH and FADH2)
D. Terminal oxidase (It is complex IV of electron transport chain termed as Cyt c oxidase)
E. Oxygen (It is the final acceptor of electrons and gets reduced to water)
the argument that the researcher supports in this statement is that the Viruses are nonliving
Answer : Option C
<u>Explanation:</u>
Viruses are organic structures and they are often termed as "organisms at the end of life". Virus is not considered a living as it does not have a biological machinery to replicate.It is a parasite and it needs a host to replicate.
The virus tries its entry through the wounds, respiratory tracts and by passing through insects.
The complete virus particle is known as virion which consists of a nucleic acid surrounded by a capsid, Virus first attach themselves to a host through their surface.
Answer:
Carbohydrates can be described as biological molecules which are made up of carbon, hydrogen and oxygen.
Simple carbohydrates are known as monosaccharides. Example of monosaccharide includes glucose and fructose. Two molecules of monosaccharides can join to form disaccharides. Example of disaccharide includes maltose. When three or more monosaccharides join they form polymers known as polysaccharides. In this way, simple carbohydrates form larger molecules or polysaccharides. Examples of polysaccharides include starch, glycogen, cellulose etc.
It has 3 layers
an animal cell has no cell wall but a plant cell dose
it protects,support, and gives the plants their shape
Answer:
The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.
Explanation:
Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.
An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.
