CP Biology Semester 1 Exam Review

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two identical dominant alleles, represented as 'YY'.

Front

What is the role of a substrate in an enzyme-catalyzed reaction?

Back

The substrate is the molecule upon which an enzyme acts, binding to the enzyme's active site.

Front

What does it mean for a trait to be dominant?

Back

A dominant trait is one that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the genotypes of offspring from parental genotypes.

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, and include sugars like glucose and fructose.

Front

Define genotype.

Back

Genotype refers to the genetic makeup of an organism, specifically the alleles it possesses.

Front

Define phenotype.

Back

Phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles mask the effect of recessive alleles in heterozygous conditions.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the function of the active site of an enzyme?

Back

The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
