One major difference between viruses and other cells is that viral particles have nucleic acid located within a capsid.
Structure of a virusViruses are made up essentially of ribonucleic or deoxyribonucleic acids enclosed in a proteinous shell known as capsids.
This is unlike other cells in which their nucleic acids either lie freely within the cytoplasm of their cells or are enclosed in a double membrane structure known as the nucleus.
Viruses are essentially non-living when outside a living host.

Paragraph 3 describes the diagram at the top of this article. It demonstrates:
A: that energy flows in one direction beginning with light energy
B: the transportation of sugars into mitochondria
C: the Krebs Cycle
D: the Calvin Cycle
Photosynthesis involves a series of reactions including trapping of sunlight energy and the Calvin cycle through which plants make their food in the form of sugars.
What is metabolism?Metabolism refers to the sum of reactions that occur in a living organism which helps obtain energy and remove waste in order to sustain the life of an organism.
Different metabolic reactions take place in plants and animals.
In plants, energy is obtained from the sun and is used to drive photosynthesis.
The sugars made in photosynthesis are stored in roots, stem and tubers as well as in fruits.
The sugars can be broken down to produce energy in th mitochondria.
The Calvin cycle is the process that plants use to convert carbon dioxide and water to sugars
The Krebs cycle is a cycle which produces molecules which are used to produce energy in the mitochondria.
Therefore, since the diagram is not attached, the process shown can be understood from the explanation of each process in photosynthesis and metabolism.

The important biochemical process that receives a supply of NAD+ ions from the fermentation process during anaerobic respiration is glycolysis. Hence option C is correct.
What is Glycolysis?Glycolysis is the first step in both aerobic and anaerobic respiration. It takes place in the cytoplasm and involves the breakdown of glucose into pyruvate. During the process, NAD+ ions are reduced to NADH, which is an energy-rich molecule that is used in the electron transport chain to produce ATP.
In anaerobic respiration, when oxygen is not available, the electron transport chain cannot function, and the cell must rely on other processes to regenerate NAD+.
Fermentation is one such process, and it involves the reduction of pyruvate to other organic molecules, such as lactic acid or ethanol. This process regenerates NAD+ from NADH, which can then be used in glycolysis to produce more ATP.
Therefore, during anaerobic respiration, the fermentation process supplies NAD+ ions to glycolysis, allowing the cell to continue producing ATP in the absence of oxygen.
Hence option C glycolysis is correct.
