Question

Transcribed Image Text:True or False:
1- The process of cellular respiration occurs in the mitochondria
and involves the breakdown of glucose to produce ATP,
which is used as an energy source by the cell.
2- Mitochondria help the cells to maintain proper concentration
of calcium ions within the compartments of the cell.
3- The Golgi apparatus plays an important role in the process of
apoptosis or programmed cell death.
4- The cell membrane is composed of three types of substances:
Proteins (40%), Lipids (55%), and Carbohydrates (5%).
5- Phospholipids are lipid substances containing phosphorus
and amino acids.
6- Cholesterol molecules in a cell membrane are arranged in
between the phospholipid molecules.
7- The lipid layer of the cell membrane is a semipermeable
membrane and allows only the fat-soluble substances to pass
through it.
8- Carbohydrate molecules in the cell membrane are negatively
charged.
9- The cytoplasm of the cell is the jelly-like material formed
60% water.
10- The endoplasmic reticulum is of two types, namely rough
endoplasmic reticulum and smooth endoplasmic reticulum.
11- The rough endoplasmic reticulum is concerned with the
synthesis of proteins in the cell.
12- The smooth endoplasmic reticulum It is also called the
granular reticulum.
13- Smooth endoplasmic reticulum is also concerned with
catabolism and detoxification of toxic substances like some
drugs.

The chocolate-covered cherries are like a mini cake with a cherry inside. The cake comprises a combination of sucrose (powder sugar), butter, cherry juice, and an enzyme (invertase). While stored at 5.00C, the sucrose hydrolyzes to produce glucose and fructose. The mixture of the glucose and fructose is a liquid called invert sugar. Below you will find the concentration of sucrose in the cake as a function of time. For the cherries to be edible, more than 80% of the sucrose must be hydrolyzed. Before you start to answer the question, create a data table that comprises sucrose concentration in units of moles per liter.
