In general what is the life cycle of a virus

Biology

KonstantinChe [14]3 years ago

Answer:

Explanation:Many viruses follow several stages to infect host cells. These stages include attachment, penetration, uncoating, biosynthesis, maturation, and release. Bacteriophages have a lytic or lysogenic cycle.

The life cycle of viruses may be divided into the following stages:

1. Attachment

Attachment is a specific binding between viral surface proteins and their receptors on the host cellular surface. This specificity determines the host range of a virus. For instance, the human immunodeficiency virus (HIV) attacks only human's immune cells (mainly T cells), because its surface protein, gp120, can interact with CD4 and chemokine receptors on the T cell's surface (Figure 1-E-3).

2. Penetration

Following attachment, viruses may enter the host cell through receptor mediated endocytosis or other mechanisms.

3. Uncoating

Uncoating is a process that the viral capsid is degraded by viral enzymes or host enzymes.

4. Replication

Replication involves assembly of viral proteins and genetic materials produced in the host cell.

5. Release

Viruses may escape from the host cell by causing cell rupture (lysis). Enveloped viruses (e.g., HIV) typically "bud" from the host cell. During the budding process, a virus acquires the phospholipid envelope containing the embedded viral glycoproteins.

ermentation reactions A. completely oxidize glucose to carbon dioxide and water B. often require the reactions of glycolysis to
goldenfox [79]

Answer:

E. two of the above are correct

Explanation:

Fermentation reactions are processes that occur without the presence of oxygen and promote the release of energy (ATP) anaerobically. For these reactions to occur, glycolysis and reduction of pyruvate must occur.

These reactions allow the regeneration of NAD + that is necessary for the breakdown of glucose during the process called glycolysis, which is primarily responsible for the production of ATP. NAD + is regenerated from NADH.

With that, we can conclude that the correct options are:

B. often require the reactions of glycolysis to provide energy as ATP

C. supply NAD for the oxidation of glucose

During photosynthesis,energy from sunlight is used to start a reaction. And water.
olganol [36]

Answer:

Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen gas

Explanation:

Each molecule of glucose essentially “stores” up to 38 molecules of ATP which can be broken down and used during other cellular reactions. ATP, or adenosine triphosphate, is the form of chemical energy cells use to function.

What is the third type of variation in Mendel's theory?
Nikitich [7]
The three most important Mendel law is the law of dominance, law of segregation, and law of independent assortment. The law of dominance is when a trait is more recived or more dominate than other trait. For example a flower, if a flower is red most of the flowers will be red, but one will be white. The white flower has a recessive trait. The law of segregation is when a offspring randomly receive one allele of every trait from each parent. The law of independent assortment states that just because you received one allele doesn't mean another dominate allele will be passed also.
