CA1 Common Assessment Review

Enzymes ________ (select 2)

• are lipids

• are proteins

• increase activation energy

• lower activation energy

Answer explanation

Enzymes speed up chemical reactions by lowering the activation energy (which also increases the rate of those reactions)

In the lysogenic cycle, the virus ______

• undergoes meiosis

• ruptures the host cells membrane

• undergoes mitosis

• incorporates its DNA into the Host's DNA

Answer explanation

the lysogenic cycle is the dormant cycle where the viruses DNA hides within the host DNA

In the lytic cycle, the virus ______

• undergoes meiosis

• ruptures the host cells membrane

• undergoes mitosis

• incorporates its DNA into the Host's DNA

Answer explanation

lytic - tic tic boom!, lytic cycle causes the host cell to rupture which releases more viruses
