Answer:

b. Active site

Explanation:

The active site of an enzyme, also called the active center, is the area of the enzyme to which the substrate binds, so that the reaction occurs.

Enzymes are proteins. Certain characteristics in its tertiary structure are those that determine the shape of the active site of the enzyme, and therefore delimit the substrates on which the enzyme can act. In other words, the three-dimensional structure of the enzyme also determines the structure of the active site, and gives specificity to the enzyme, which can only act on certain substrates: those capable of binding to its active site.

Many times, the active site has the shape of a cleft or a cavity in the structure of the enzyme. The active site is usually formed by side chains of specific residues, and it is for this reason that it often has a three-dimensional structure different from the rest of the enzyme. The structure and composition of the active center is configured so that only a certain substrate has sufficient affinity to bind to this area of the enzyme

What characteristic of water causes water to stick to the side of a test tube?

bazaltina [42]

Answer:

The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).

Explanation:

Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.

- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.

- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.

- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.

The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

If there was no glucose available for plant and animal cells what would happen?

joja [24]

Answer:

Glucose is a sugar that many plants, animals and fungi use for energy. In plants, glucose is produced as a result of photosynthesis. Plants need the energy glucose provides in order to grow and reproduce. ... Without glucose, plants would not have the energy necessary to grow, reproduce or carry out cellular respiration.
