The normal shape of an enzyme is as shown in structure A. If the enzyme's shape changes to that shown in structure B, what are t
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.

torisob [31]
<span>You needed a quick boost of energy - MONOSACCHARIDE

You wanted to grow strong nails, you haven't eaten in days - PROTEIN

You wanted to grow healthy hair - PROTEIN

You had a race tomorrow afternoon - POLYSACCHARIDE 

You were getting ready for hibernation - LIPIDS

You wanted to get bigger muscles - PROTEIN 

Your meal will be in a week - LIPIDS

CARBOHYDRATES include monosaccharide and polysaccharides. They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants. 

PROTEIN s</span>peeds up chemical reactions by lowering activation energy. It is used to form bones and build muscles. It is m<span>ade up of an amino group, a carboxyl group, and an R group.

LIPIDS can be saturated or unsaturated fatty acids. They are not soluble in water however they provide long-term energy storage for animals. </span>

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of
8_murik_8 [283]

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

  • As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked.
  • This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.
