Varvara68 [4.7K]

Answer:

There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding

Explanation:

An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.

Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding.

vaieri [72.5K]

Answer:

Vision

Explanation:

Sensory cells may detect the information like taste, touch, hear and vision by the presence of receptors located on their surface.

Hyperpolarisation may be defined as the change in the cell's membrane potential towards more negative. The sensory vision cells are associated with the hyperpolarisation of cells and makes the cells environment more negative  in response to the stimuli.

Thus, the correct answer is option (d).

kupik [55]

Considering the choices;

A. blood glucose level and pH

B. amount of light and temperature

C. amount of light and pressure

D. temperature and pH

Answer;

D. temperature and pH

The two factors affect an enzyme's operation the most is the temperature and pH.

Explanation;

Enzymes work best at optimum pH and temperature.

At low temperature for example the enzymes are inactivated while at high temperatures enzymes are denatured.

At optimal temperature and pH; the chemical reaction rate is optimal.
