4. How do enzymes affect the speed of a chemical reaction?

Answers

Answer 1

Answer:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

A To protect
B To attach to a host cell
C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA

Answers

Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.

Surface protein on the influenza virus is needed for attaching to the host cell.

The surface protein of viruses can be explained as:

In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.

Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.

The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.

Therefore, option B to attach to the host cell the surface proteins are needed.

The ice cubes represents the solar energy.

What is Solar energy?

Solar energy is the radiant heat and light from the Sun that is captured by a variety of technologies, including solar architecture, solar thermal energy (including solar water heating), and solar power to produce electricity.

It is a crucial source of renewable energy, and depending on how solar energy is captured, distributed, or transformed into solar power, its technologies are often classified as passive solar or active solar. Utilizing photovoltaic systems, concentrated solar electricity.

A building's orientation toward the Sun, the use of materials with favorable thermal mass or light-dispersing qualities, and the creation of naturally ventilated rooms are all examples of passive solar approaches.

Therefore, The ice cubes represents the solar energy.

One side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA. What would be the complementary side’s bases? How many amino acids would that sequence code for?

Answers

Answer:  The arrangement of these nitrogen bases contains the code for

genetic traits. These bases are arranged in a particular

sequence, such as TGCATTCA. The sequences of DNA can vary

from several hundred bases to a million or more bases.

Explanation: put this and my teacher said amazing  

The complementary side’s bases if one side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA are: CCTGAAATGCGT.

What is the complementary sequence?

Thus, the complementary nitrogen base sequence of GGTACTTACGCA is CCTGAAATGCGT. It is because the complementary nitrogen bases pair up: A always pairs with T, and C always pairs with G.

The sequence codes for 4 amino acids. Every three nitrogen bases code for one amino acid. So, since there are 12 nitrogen bases, the sequence codes for 12/3 = 4 amino acids.

To determine the number of amino acids coded by this sequence, first note that a codon consists of three nucleotide bases, and each codon corresponds to one amino acid. The sequence has 12 bases, so there are 4 codons: GGT, ACT, TAC, and GCA. Since each codon codes for one amino acid, this sequence would code for 4 amino acids.

Explain how DNA results in the expression of a gene using the following words: DNA, mRNA, tRNA, gene, transcription, and translation

Answers

Explanation:

in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.
