Answer:

Viruses use their own catabolic enzymes.

Explanation:

Viruses are the infective particles present in the environment which encloses their genetic material which could be wither RNA or DNA enclosed in the protein coat.

The protein coat is made of the capsomers which are arranged in the tubular structure forming capsid. The viruses do not contain the metabolic machinery of their own that is the reason that they do not have replication or transcription or translation machinery. For this they are dependent on the host organisms as they use their machinery.

Thus, the selected option is correct.

About this much of the energy released from food molecules during catabolism is released as heat:______.
lorasvet [3.4K]

About this much of the energy released from food molecules during catabolism is released as heat: adenosine triphosphate (ATP)

The Adenosine triphosphate (ATP) is the source of the energy for the use and the storage at the cellular level. The structure of the ATP is a nucleoside triphosphate, consisting of the nitrogenous base (adenine), and ribose sugar, and the three serially bonded phosphate groups

ATP is synthesized in the mitochondria is the primary energy source for the important biological functions, such as the muscle contraction, the nerve impulse transmission, and the protein synthesis

In general, the main energy source for the cellular metabolism is the glucose, which is the catabolized in the three subsequent processes—the glycolysis, tricarboxylic and acid cycle (TCA or Krebs

Antigens are Multiple Choice something made by a white blood cell to destroy a pathogen. membrane receptors on B-lymphocytes. di
Zolol [24]

Answer:

Something that an antibody or T-lymphocyte binds to

Explanation:

As per the definition, antigens are the substances or molecules that are capable of inducing an immune response. When our immune system detects any unwanted substance or molecule in our body, the specific type of antibody is made against that antigenic substance and the antibody made against it binds to the antigen so that the other immune cells can recognize it and destroy it and protect us form its harmful effect. T-cell are also involved in recognizing antibodies and specific T-cell can bind to the antigen.

which statements about oxidative phosphorylation are true? the mechanisms of phosphorylation and oxidation are directly coupled.
arlik [135]

The true statements about oxidative phosphorylation are the mechanisms of phosphorylation and oxidation are directly coupled.

<h3>What is oxidative phosphorylation ?</h3>
  • An electron transfer chain that is fueled by substrate oxidation and connected to ATP generation via an electrochemical transmembrane gradient is known as oxidative phosphorylation (OXPHOS).
  • Cells employ enzymes to oxidize foods in the metabolic process known as oxidative phosphorylation, electron transport-linked phosphorylation, or terminal oxidation, which releases chemical energy to create adenosine triphosphate. This happens inside mitochondria in eukaryotes.

Steps in Oxidative Phosphorylation

  • Electron Transport using NADH and FADH2. Near the start of the transport chain, reduced NADH and FADH2 transmit their electrons to molecules. ... the splitting of oxygen into water, proton pumping, electron transport, and ATP synthesis.

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for
Bond [772]

Answer:

Hair length: hh

Hair color: Bb

Hair Texture: RR

Explanation:

In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.

The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from <em>homzygous.</em>

The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous <em>dominant</em>, which means there will be two of the same dominant alleles, so, RR.
