Summative 2

Question 1

What are the reactants and products of photosynthesis?

Answer 1

Carbon dioxide and water are the reactants and glucose and oxygen are the products

Question 2

What happens in the two phases of photosynthesis?

Answer 2

Light Dependent Reactions- Convert sunlight to chemical energy,takes in H2O and produces 02, and sends H+ ions to the light independent reactions. Calvin cycle uses ATP to combine the H+ ions with CO2 to produce glucose in addition to water and carbon dioxide, photosynthesis requires light and colorful plants gather the suns energy with light absorbing molecules called pigments.

Question 3

Where does photosynthesis occur in the cell?

Answer 3

Inside the chloroplast

Question 4

What is a concentration gradient?

Answer 4

The process of particles in the membrane from one side to the other

Question 5

Where does cellular respiration occur in the cell?

Answer 5

In the cytoplasm then moves into the mitochondrion

Question 6

What are the three types of carbohydrates?

Answer 6

Monosaccharides, disaccharides, and polysaccharides

Question 7

Explain the process of dehydration synthesis and hydrolysis

Answer 7

Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers.

Question 8

What is denaturation?

Answer 8

Denaturation is the alteration of a protein shape through some form of external stress (for example, by applying heat, acid or alkali), in such a way that it will no longer be able to carry out its cellular function.

Question 9

What are catalysts?

Answer 9

A substance that speeds up a chemical reaction, but is not consumed by the reaction

Question 10

What are enzymes?

Answer 10

Breaks stuff down into tiny particles which can be converted into energy

Question 11

What is the difference between an anabolic and catabolic reaction?

Answer 11

Catabolic releases energy, anabolic requires energy

Question 12

Compare and contrast kinetic and potential energy

Answer 12

Kinetic energy is the energy possessed by a body and its movement. Potential energy is possessed by a body and its position

Question 13

What happens in each of the three phases of cellular respiration?

Answer 13

1. Glycosis- Happens in cytosal, breaks glucose in half, produces 2 ATP molecules and oxygen is not required 2.Citric Acid Cycle- Happens inside mitochondria, oxygen is required, completes the breakdown of glucose releasing CO2 and produces 2 ATP molecules 3.Oxidative Phosphorylation- Happens inside the mitochondrion, oxygen is required and produces 34 ATP molecules

Question 14

Where does cellular respiration occur in the cell?

Answer 14

In the cytoplasm then moves into the mitochondrion

Question 15

Describe the structure and function of proteins

Answer 15

They are involved in structural support and fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer

Question 16

How are enzymes compared to keys in the lock and key analogy?

Answer 16

The lock is the enzyme and the key is the substrate. Only the correct sized key(substrate) fits into the key hole(active site) of the lock(enzyme).
